Changed globbing patterns to support subfolders at any level

It's me again :-)

I like to organize my code in many files and organize them in subdirectories.
For example:
Changed globbing pattern to /**/ in order to support subfolders at any level
Merge branch 'patch-1' of github.com:tonypolik/generator-ionic into patch-1
Merge pull request #14 from tonypolik/patch-1
