Subject: [PATCH] Add basic support for ANSI color escape codes.

Nim's `terminal` library provides ANSI terminal escape support, but
only when writing directly to a File handle. This commit adds the
`term{FG,BG}` procedures and `termReset` constant to help with embedding
ANSI escape codes in string data.
