.Xresources: embed color scheme instead of including it.

KDE tends to load .Xresources from a random working directory, so I
can't write path to included file without using my specific user name.
.config/awesome: minor updates to window management (mostly code reordering).
.config/awesome: battery widget: fix power rate handling in the "model" and improve the "view" a bit.
.config/awesome: Chrome -> FF.

In pursuit of a lower memory footprint.
.config/awesome/**/*.lua: rtrim.
