Lots of loader improvements:

* Stop logging every single item path we evaluate, even if it's unchanged (greatly reduces log footprint)
* Console output is now more precise as to whether an item was updated or added, and why
* Modified dates shown in the console are now more prettily formatted
* Fixed an issue where renames (which do not change the revision or date modified) would not be synchronized correctly
* Fixed an issue where if an item differed only be revision, but had an identical modified date, it would not be synchronized correctly
* Don't call PasteSyncItem if we are not forcing an update, which should make things slightly faster
* Log debug console output as Info in the Sitecore log, so it does not get lost for people using default log settings
Fix exception when renaming an item with children if a directory had already been deleted
