Update dxr.css
Update dxr.css
Added a .css class for icons and a coresponding css.png into the icons directory.
Fixing missing css rule and a few other things
I fixed the dissapearing .c icon class and it's appearance in other places where it shouldn't.
I changed a great bit of icons.css since it had outdated css rules.
Moved .icon-container there and applied rules that are common for all icons to it.
Changed folder.html in order to load new icon classes instead of a style property.
Fixing small details.
Moved the inline style form path_line.html into dxr.css as `.result-head a`.
Removed spaces from <a> in path_line.html
Merge branch 'master' of https://github.com/mozilla/dxr
Fixing bugs: 1053423, 1052524 and 965652
For 965652:
	dxr.css :
	Added a rule for .code code a in order to show availability of context-menus but limited in order not to overwrite a rule somewhere else.
For 1052524:
	file.html :
	Added the .icon class to all anchors in the panel
	dxr.css :
	Removed padding form (.panel section a) since it blocks the added .icon class
For 1053423:
	context_menu.html :
	Added the .icon class to all anchors in the list in order to have a pseudoparent class and eliminate a lot of repeating in icons.css
	dxr.css :
	Removed padding from (.context-menu a) since it blocks the added .icon class
	icons.css :
	Made a lot of changes and removed the repeating rules for background since they are no longer needed because of the .icon class
Other:
Fixed .build in icons.css that I missed it the last time.
Added comments in icons.css in order to show rearanged sections.
Added a lot missing icon classes which are referenced in .panel and .context-menu .
Since the .panel icons that are always shown are probably going to be redone they are commented out untill the time has come.
That's about it. Will mention if I find something else.
Fix typos.
Increment format version.

The changes to file.html need it in order for the new CSS to kick in properly.
Let folder context menus inherit the same padding as code context menus.
Indicate existence of context menus with cursor change: fix bug 965652. Fix repeated Diff icon: fix bug 1052524. Polish look of context menus: fix bug 1053423.
