Track if hours were worked from the office or from home

[jneidel]

Timecard reviews have complained about both:

• not enough days in the office logged
• wrong days in the office logged

To remedy this add the functionality to keep track if hours were worked from home (default) or the office.

This output should be only be included in the timecard and hour list views if it was from the office.

--office to mark hours at creation with hour add as worked from the office.

Implementation notes

• data file for office attendance, year->week->dotw->bool
• home office is the assumed default
• --office flag on hour add
• --office flag on note add
• --no-office/--office flag on hour edit
• --no-office/--office flag on note edit
• timecard splits by office attendance
• classic timecard splits by office attendance
• note list shows a hint about office attendance
• Maybe: hour list shows a hint about office attendance
