very cool project

[Stephen I. <ste...@gm...>]

I added the following features. I would like to submit my changes.

1) windows port:
    a)  converted cwd to use "/"
    b)  added 'pwd' builtin command
2) save editor button using ajax. Use case: I am editing a file and don't
want to exit editor mode, basically want to see changes to file w/o
exiting.

3) added environment variable section in config.php, needed for hosted
systems with no login. Use case installing php reports.

config.php
[environment]
COMPOSER_HOME = "${DOCUMENT_ROOT}/tmx/composer"
