That's what allow rake spec to work.
Gemfile.lock removed (previously only ignored)

As per best practice in lib development.
Move spec sample files into subdirectory
Handle basic escape sequences in values

This is more or less a hack based on information gleaned from

http://developer.apple.com/library/mac/#documentation/cocoa/conceptual/LoadingResources/Strings/Strings.html

It only escapes NLs, CRs, tabs, double quotes and backslashes.  Unicode
escapes are not handled because I don't need them right now.  In the
case of unknown characters it does not remove the backslash which I did
to be minimally invasive, however I did not confirm the actual behavior
on Apple's side.
