audible_bell, autohide_mouse, scroll_on_keystroke, etc.

[Vic Fryzel]

I added a bunch of new features with relevant RC configuration
options. The full list now includes:

allow_bold=false
audible_bell=true
autohide_mouse=true
font=Envy Code R 10
fullscreen=false
num_scrollback_lines=-1
scroll_on_keystroke=true
scroll_on_output=false
transparent_bg=false
url_regex=(ftp|http)s?://[-a-zA-Z0-9.?$%&/=_~#.,:;+]*
visible_bell=true
window_height=500
window_width=500
word_chars=-A-Za-z0-9,./?%&#:_

The given values are my preferred ones, not defaults. I think these
options make the terminal much more usable. I also renamed bold to
allow_bold, just so that it's clear what the boolean is going to do.
I also fixed num_scrollback_lines, as before is was being parsed as
bool, not int.
