Make hud's menu-area text configurable

By default the hud positions a little box on top-left corner of each
table. Make the text in this box user-modifiable without touching the
source.

Most likely useful for active users and those who play with smaller
tables. On shrunk table the default box may cover some of the players'
cards.
