* Cleaned up and corrected changeView calling code to avoid initial git commit msg stuff.
* Refactored `lastCommitMsg` to `prevCommitMsg` in pipeline.

* Added `getCommitInfo` to git `IModel`.
  * Added commitInfo to Model implementation class.
* Changed `IRawGitService.getCommitInfo` to return `IRawStatus` instead of `ICommitInfo` directly.
* Changed `IGitService.getCommitInfo` to return `IModel`.
  * This was required because it expects a status when performing a git operation from the client (not really documented nor obvious).

* Added `Repository.getLog(ILogOptions)` for getting the previous commit msg, but allowing extensibility.
  * Added `ILogOptions` with single `prevCount` for extensibility of other use cases when executing `git log -1` (which gets the previous commit msg).

InProgress:

* Implementing getCommitInfo to parse possible template file, as well as parse the previous log message.
