folding selection patch for syntax/ruby.vim

[Ward Wouts]

Hi,

The following patch lets me turn on folding with 'let ruby_fold = 1' in
my .vimrc instead of 'set foldmethod=syntax'. This is nice because I
don't like foldmethod=syntax for every thing. This is also more in line
with the way the fortran, php, perl, rcs and sh implementations work.
