mail and code cleanup

_ttbp.py is now the working copy i'm using, so i don't bust the live
program.

i brought over the id code generator that i use in txtminebot to
generate random id tags for feedback subject lines. the feedback
mechanism now uses sendmail instead of writing to disk.

i also started to clean up some of the larger text blocks by using here
documents.

bin/util.py
