Allow settings to be set before compiling a file

[tgolla]

I went to try Crunch 2 on an existing LESS project and immediately got this error the solution to which the solution is to enable JavaScript.

The problem is that without a previously good compile of the LESS file crunch has not built a dot crunch file and CSS file which it must find to display the setting for the LESS file which allows you to enable JavaScript.

The solution for me was to build an empty LESS file, compile it, edit the .crunch file changing the filename to my LESS filename and renaming the CSS file.

Maybe the application could be altered to allow access to the file setting before these conditions (good compile, existing CSS file) are met.

This has come up elsewhere and it's a good change to make. Will do and update this issue when that's implemented.
