* create_dispatcher() w/ is_ssl determined by url instead of sslopt

* added .lower() (per @rm-you's suggestion)

* create_dispatcher() w/ parse_url()-derived is_ssl

* Fix failing test, missing wss

Was digging through the code base the past few days as it's been an excellent aid in learning about Websockets and TCP. Noticed _create_sec_websocket_key was getting called twice per ws.connect method. I may be missing something, but thought I would bring it to your attention in case it's an artifact or something. Best Regards!

* rel example

* tweaked rel example for linter

* added rel note to examples.rst

* slightly more compact example

* added example header

* matched wording

* _socket.recv(): _recv() except socket.error - changed or to and; added except TimeoutError - raise WebSocketTimeoutException

* _app - custom dispatcher check_callback() integration (and fixed pyevent compatibility): WrappedDispatcher (for use with generic event dispatchers such as pyevent and rel); create_dispatcher() accepts dispatcher kwarg (default None), and if it is specified, returns a WrappedDispatcher; use create_dispatcher() (passing specified dispatcher if any) every time (regardless of dispatcher specification)

* Add clarifying comment, rerun CI tests

* Add space to make linter happy

* working reconnect

* rmed logs

* added _logging.warning() disconnected/reconnected notifications to handleDisconnect()

* moved connect notification and dispatcher.read() (if doread kwarg [default False] is True) to setSock() (prevents those lines from running on ConnectionRefusedError)

* run_forever(): reconnect kwarg now specifies sleep() time (defualt 5)

* handleDisconnect(): fixed log msg

* run_forever() refactor: stabilized stack frame count (at least in rel mode); added stack frame count to disconnect (warning) log; grossly oversimplified ;)

* dispatcher simplification via DispatcherBase and DispatcherBase/WrappedDispatcher.timeout()

* _logging: info(); enableTrace() supports level kwarg (default "DEBUG")

* handleDisconnect() uses info() log

* Fix linting errors

* moved timeout() from Dispatcher to DispatcherBase (thus also applying to SSLDispatcher)

* reconnect()s for DispatcherBase (uses while loop) and WrappedDispatcher (uses timeout()); setSock() reconnecting (default False) kwarg - if reconnecting, skip handleDisconnect(); handleDisconnect() calls dispatcher.reconnect()

* custom_dispatcher switch in handleDisconnect()

* WrappedDispatcher constructor registers keyboard interrupt signal

* DispatcherBase.reconnect(): wrapped while loop in KeyboardInterrupt try/except

* fixed lint errors

* _app: RECONNECT (default 5) and setReconnect() setter; WebSocketApp.run_forever() reconnect kwarg defaults to RECONNECT

* tests.test_app: ws.setReconnect(0) (may fix test stall issue)

* oops, added setReconnect import to websocket __init__

* blank line for linter

* linter line

* added rel to setup extras_require{test}[]

* adjusted testRunForeverDispatcher() to use rel (including dispatch())

* setup: moved rel dep from extras_require{test}[] to tests_require[]

* meh trying install_requires[] (tests_require[] depped??)

* set RECONNECT (run_forever() reconnect kwarg default) to 0 (can be altered with setReconnect()) to preserve old (non-reconnecting) default behavior for existing integrations

* rmed rel from install_requires[] (only added for tests, and was not working...)

* test_app: rmed ws.setReconnect(0) (0 is new default)

* run_forever() reconnect->RECONNECT fallback in func instead of kwarg default

* test_app: disabled rel import (unsure how to set up test dependency) and testRunForeverDispatcher() (also not working previously afaik)

* linter fixes

* linter comment spaces

* run_forever() returns False to pass testRunForeverTeardownCleanExit test

* run_forever() returns False unless error (handleDisconnect() changes to True before calling on_error callback)

* rval->self.has_errored
