ANSI coloring breaks git branch call

[diegotori]

In GitAdapter.gitCurrentBranch(), when it looks up the current repo's branches, if the current bash shell has LSCOLORS enabled, then it will add the following output to the branch call:

Running [git, branch] produced output: [some-other-topic-branch�[m
* �[32msome-topic-branch�[m 
Running [git, push, --porcelain, origin, �[32msome-topic-branch�[m] in [/Users/diegotori/as_projects/some_app] 
Running [git, push, --porcelain, origin, �[32msome-topic-branch�[m] produced output: [] 
Running [git, push, --porcelain, origin, �[32msome-topic-branch�[m] produced an error: [fatal: remote part of refspec is not a valid name in �[32msome-topic-branch�[m] 
:some_app:app:preTagCommit FAILED 

The way to strip out all coloring without resorting to regexes is by calling "git branch" with the "--no-color" option, thus sanitizing the output.
