Add error domain, TumblerThumbnailFlavor and thumbnail helper functions.

This commit adds the TUMBLER_ERROR_DOMAIN and TUMBLER_ERROR defines and
a TumblerErrorEnum with currently only containing TUMBLER_ERROR_FAILED.

Also new is the TumblerThumbnailFlavor enum type, together with a few
utility functions related to creating thumbnails:

  - tumbler_thumbnail_get_flavors() returns all flavors supported by
    the current build of tumbler,

  - tumbler_thumbnail_flavor_get_size() returns the size corresponding
    to a flavor (e.g. 128 for TUMBLER_THUMBNAIL_FLAVOR_NORMAL),

  - tumbler_thumbnail_flavor_get_directory() returns a GFile pointing
    to the flavor directory (e.g. $HOME/.thumbnails/normal/ for
    TUMBLER_THUMBNAIL_FLAVOR_NORMAL),

  - tumbler_thumbnail_get_file() returns a GFile pointing to the
    thumbnail destination file of an URI and a flavor,

  - tumbler_thumbnail_create_and_open_file() tries to create such a
    GFile and also tries to open it for writing, returning the
    GFileOutputStream if possible.
