Wishlist: recursive watching for a file pattern

I want to run a command whenever a filename matching a particular glob pattern (*.rst) changes in a directory tree.

I can watch the directory tree recursively with server.watch('directory/'), but this triggers for other kinds of files as well.

I can watch for a glob pattern (*.rst), but this doesn’t support recursive globbing (yet).

Possible solutions:

• implement '**/*.rst'-style globbing (perhaps backport the feature from Python 3.5?)
• add a filter argument so I could say server.watch('.', filter=lambda fn: fn.endswith('.rst'), func='make html')

Note that a solution to manually use an external library for file globbing, like the one suggested in the manual, is unsuitable because it would not pick up newly-created files or subdirectories.

I’ve added an ignore parameter on watch https://github.com/lepture/python-livereload/commit/26c70a709b6b74dae02c6a4548b393255c08cf59
