Got the assets to display for every argument using mustache

Still rough, but it works.  Don't know if I should be displaying the
assets for each argument using mustache as well.  Steve if you can shed
some light on me.
Added textarea on Script Exe page; Added "more details" button

Also fixed a few style issues
Fixed bux with textarea
Working on required arguments, script text status is working

Script test status is working, but it won't display them realtime, it
displays all the lines after the whole script has finished
ScriptExecution Page finished.  Both Required and Optional Arguments

The page requires you to fill in all the required assets, but doesn't
care whether or not you fill the optional.  Trevor is going to work on
limiting the assets to 3 and overflow:scroll for anything >3.  The
Script status is working, but the only problem is that it will not
update until the script has finished executing.
Add a Clear Log button

So the output of the scripts can be cleared if needed.  Probably should
add a save log button in the future too.
Added a scroll bar for >3 assets on the script exe page
cleaned up some of the HTML, especially on the project details page. Added back in the 'details pane' dropdown on assets.
