Added P,A,M characters to bigclock and added 12hr and seconds support to bigclock via `bigclock_12hr` and `bigclock_seconds` in the config.

Image has bigclock_12hr and bigclock_seconds enabled.
Farsi characters for P,A,M are blank since I don't know what it would look like in their language. (should i have just used the english characters as a placeholder?)

`drawConfinedLabel` didn't take into account the starting x axis
when checking to break for exceeding `max_length`.
This should fix the box title not appearing on
terminals with larger column counts.
