New: XcodeCapp 3 tweaks...

- Renamed XcodeSupport to .XcodeSupport.
- Added "Reset Project" to menu, it closes the project in Xcode if necessary, removes .XcodeSupport and .xcodeproj, then reloads.
- Added separate preferences for showing errors panel on warnings/errors. You may not want to see the panel if there are category warnings.
- New status icons (again).
- If an error occurs, the status icon turns red when all processing is done.
- Reworked notifications. Objective-J parsing is notified when done. Xib conversion notifies at beginning and end, because it typically takes a few seconds. Individual file notifications are suppressed if a project is being loaded.
