Gh394 git history review

#394 
use this message format:

flex_client.team.git.action.history.ui.historyTextArea = commit {0} \nAuthor: {1} {2}\nCommitter: {3} {4}\n{5}\n{6}\n{7}\n{8}\n\n<b>{9}</b>

flex_client.team.git.action.history.ui.parents = Parent: {0} {1}
flex_client.team.git.action.history.ui.childrens = Child: {0} ({1})

remove -> flex_client.team.git.action.history.ui.branches = Branches:
remove -> flex_client.team.git.action.history.ui.tags = \nTags: {0}.
remove -> flex_client.team.git.action.history.ui.longMessage = \n\n<b>{0}</b>

author & committer can be send from server with this format: name <email>
because I see that it is used this way everywhere on client (see GitService.getStageAndUnstageFiles)
