Python: detect virtual environments for documents and projects

After opening a document or project the directory hierarchy is looked up
for a Scripts/(activate && python.exe) on windows or bin/(activate &&
python) on unix. This is the usual structure of python virtual
environments. If such a folder is found add the python from that folder
to the list of configured interpreters in the settings, set it as the
current interpreter for the project and try to open the corresponding
language server.
