cleaned up interface for timesheets

[#1]

Description -

Why is this feature important to you - because i like to log my hours

How would you like the feature to work - like something that has been tested extensively

Current Behaviour - clarify how to add, delete, hide jobs. Rolling up a task just to hide the hours row is silly. The add remove icon look and feel as well as functionality is difficult to decipher. initially un-clear how to search available projects or projects just within the timesheet. Missing clear way to sort. Missing "tool tips" theres no rollover hints on links and icons.
