Speed up touching, make shell escaping more robust. #48

1.

Shellwords is part of the ruby stdlib, and built for proper shell escaping.

2.

The touch command can receive multiple files, and can even ignore nonexistent files with the POSIX-compliant -c option. Doing 1000 files per invocation dramatically sped up this phase of precompilation for me. On an app with just under 7k files under public/assets:

Before:

$ bundle exec rake RAILS_ENV=development RAILS_GROUPS=assets assets:precompile touching (nil): 88.8947s compiling (nil): 70.7533s touching (false): 0.0000s generating (false): 6.5764s

After:

$ bundle exec rake RAILS_ENV=development RAILS_GROUPS=assets assets:precompile touching (nil): 0.9903s compiling (nil): 68.2418s touching (false): 0.0000s generating (false): 6.4802s
