More Python snippets

I think I don't have any of the default snippets because they've been
moved to a separate bundle; but maybe that's ok, I'll just create the
ones I got used to while I was using SnipMate.
Snippets for .travis.yml files
Handle grep output
Handle some more of my projects
Better Python autoindent
Newer LESS syntax (not sure I need it)
XPDL files are XML, so I want fdm=syntax
Custom colors for cursorcolumn
