Resource manager layout with older Themes

[Timo-Breumelhof]

Description of bug

I noticed that on "older" skins the Resource manager looked a bit weird.
See:

After some research I found that those Themes are not forcing

CSS:
box-sizing: border-box;

And due to this the Search box moves to the next line.

This can be fixed using this CSS:

.rm-container *{
	box-sizing: border-box;
}

As in many cases it's not feasible to switch an older Theme to use border-box.

Steps to reproduce

See: https://youtu.be/2-aCW80VxWQ

List the precise steps to reproduce the bug:

1. Copy the attached Theme to your test installation
   40F-Test.zip
2. Set the Theme as the theme for a test page
3. Place the Resource manager in the "ContentPane"
4. See the issue
5. Now move the module to the "BorderBoxPane" and see it's fixed.
   (this pane has CSS that forces it's content to border-box)
