KRACOEUS-7181: fixed additional cosmetic issues, and added a posible edi...

1.) made several cosmetic updates, believe i have the look as close as I can get to the mocks. 

2.) I have added a potential solution to add the edit/cancel/save functionality to the collection lines, which I would like some feedback on.   It has been working fine with the exception of the cancel button, which is not reverting back to the previous state (the state before the edit button was clicked), on a maintenance document I would use the old maintenance data object to get the previous state, I am not sure how to do this on a transactional document.  Any input would be appreciated.

3.) I have hidden the "added by" field until attachment is saved, as the timestamp and updateUser aren't created until then.  If we want this field added as soon as the line is added to the collection we will have to save the line to the db when it is added to the collection (which might be what we want to do?).
