extend vt100.js to support xterm 256 colors

[GoogleCodeExporter]

i really like my vim/screen/mutt/finch colors as defined by my server conf 
files. 

since vt100 emulators can support 256 colors by interpreting additional escape 
codes sent by the server, i went ahead and implemented this on my local copy of 
shellinabox.

the only changes i made were in vt100.js and some of the included css files.

with these updates, i can run screen/vim/mutt with full 256 color support as 
per the color themes on the server. the css files i changed merely provide the 
base 16 system colors as well as a default background/front-color.

perhaps others would like this feature as well?

and btw, this is a great project, thanks for your work. i learned a lot about 
terminal emulators going through your code...

i made the same changes in color.css to styles.css as well. basically i just 
matched the 16 system colors to that of Terminal.app as found here:

attaching newer vt100.js and styles.css, adding my changes into the version in 
trunk, rather from the tar.gz versions which are outdated compared to trunk.

I have tested the vt100.js/styless.css today. They work great.

Thanks!

These patches are great. There still a few things that need to be improved, 
though.

* The bgAnsi* classes in your color.css are setting 'color' when they should be 
setting 'background-color'.

* An off-by-one error in two places in vt100.js is preventing ansi0 and bgAnsi0 
from being used at all.

* A logic error in vt100.js is causing it to incorrectly set the foreground 
color to ansi7 for text which has the default color + bright attribute.

* When setting text to bold, you used "text-weight:bold;". It should be 
"font-weight:bold;"

I have fixed all of the above, and attached the updated files.

Please provide a patch file instead of individual files.

Would like to add that this is a highly anticipated feature - I had installed 
Shellinabox but removed it because irssi became unusable.

I've implemented this different way... What about ESC]4 ? we need to be able to 
alter the array of colors. This requires change in doControl's logic. not 
sharing vt100.js because of mixed style

ESC]4 wouldn't follow the standard for control sequence (because it ends with 4)
and would be nuisance to deal with in applications.

I would really love to see this in the main repository. Any chance of that 
happening soon? It's the only thing preventing us from using it in out VPN 
portal.

The best way to see your change integrated is to pull the repository, make your 
change and send me a pull request.

Lots of people know how to edit javascript files, but not all know how to 
create patches. As such, why don't you (project members) just make the patch 
using the suggested files?

Hi, we have 256 color support added in our maintained fork. I think it works ok 
:)
