Subject: src/calcurse.c: Support count prefixes for motions

Add a global count buffer to our main loop and pass it to keys_getch()
as well as to all motion commands.

This enables some fancy shortcuts:

* Type "2l" to jump to the day after tomorrow.
* Type "4k" (or "28l") to move forward four weeks.
* Type "2$" to go to the end of next week.
