Fix package : add fastentrypoint to manifest

[jbardo]

Hello @Konubinix ! :)

click-project package install with pip seems broken in 0.7.0:

$ pip install click-project==0.7.0 --no-cache
Defaulting to user installation because normal site-packages is not writeable
Collecting click-project==0.7.0
  Downloading click-project-0.7.0.tar.gz (103 kB)

including fastentrypoint.py to MANIFEST.in seems to fix it.

note: not sure if symlink name 'fastentrypoint.py' without 's' is on purpose, so leaving as it is (original file is 'fastentrypoints.py' though).
