Fix padding problem.

[gustavom]

After installing update 1.8, the file icons appear with the 'padding' problem. I applied a css adjustment to fix this.

Does your fix address nested padding as well?

I wrote a little code to address the padding issue as well. My code is as follows:

#project-files-container li a .jstree-icon {
	left: -4px !important;
}
#project-files-container li.jstree-open a .jstree-icon {
	left: 8px !important;
}
#project-files-container li.jstree-open li.jstree-open a .jstree-icon {
	left: 18px !important;
}

It only handles two nested folders, but I've never had more than two to worry about. If someone has a better solution please comment.
