Fixed bug in gl diff that occured when trying to diff a directory (now you get the appropiate error msg)
Sort output of gl_status so that it looks nicer
Print err and out if a gl command fails in test_e2e
Improvements in comments + removed IGNORED_STAGED check which is now reported as IGNORED by gitpylib
Minor fix in test_e2e msg
More file tests that assert that cmds are relative
