Grep in Project TextMate command from http://henrik.nyh.se/2007/06/grep-in-project-command-for-textmate

README

Grep in Project.tmCommand
=========================

Orginally from http://henrik.nyh.se/2007/06/grep-in-project-command-for-textmate

* Added a few more patterns of files to ignore
* Use 'git grep' instead of 'find | xargs grep' for quicker searches in git projects
