ncdirect_init(), notcurses_init() should reset attributes

[dankamongmen]

At least with ncdirect_init(), it is plain that we're not resetting attributes, and thus preserving them from any prior state. They should almost certainly be reset, I am thinking.

Verification: I added some ncdirect code to the end of direct.c. It behaves differently based on whether I leave in or comment out the prior code.
