MediterraneanNight*: gtk-3.0: Set gtkwindow color as @theme_fg_color.

This patch comes from a hint from "debianxfce11" at:

    http://gnome-look.org/content/show.php?content=156782&forumpage=14

Note that only two themes are patched, while we should actually patch all of
the themes.
MediterraneanNight: Add support for header bars.

Include instructions for the panel.
gtk-2.0: terminal: Disable specific the notebook tab styling.

This is "less bad" than what we had, but still quite far from the ideal,
honestly.

Oh, and those pesky trailing whitespaces.  Still not certain if I will
remove them, unless I end up as the maintainer of this theme (which I would
not like to).
Fix whitespace and `^M` control characters normally generated by Windows

The original files contain `^M` control characters that usually originate
from editing files in Windows.  The dreaded dos line-endings. These control
characters can cause errors on Linux machines.

Extra whitespace at the end of lines is also removed.

[rbrito: Fixed commit message to have at most 80 characters.]

Make background transparent by default for all gtk3 widgets
Merge pull request #3 from Dvad/upstream-next

Correct tab and header bar colored square.
Remove executable bits from non-executable files.
Automate removal of trailing whitespaces.
Optimize the PNG files.

For documentation purposes, the following sequence of commands was used:

find . -iname "*.png" -print0 | xargs -0 optipng -zc1-9 -zm1-9 -zs0-3 -f0-5
find . -iname "*.png" -print0 | xargs -0 advpng -z3
find . -iname "*.png" -print0 | xargs -0 advpng -z4 -i50
find . -iname "*.png" -print0 | xargs -0 advdef -z3 -i255
find . -iname "*.png" -print0 | xargs -0 advdef -z4 -i50

Note that advpng may not always compress a PNG file (there are some
unsupported formats), but even then, advdef always recompresses them.

With current versions of adv{png,def}, the level 3 is 7zip's implementation
of the DEFLATE algorithm, while level 4 is Google's zopfli implementation.
Fix background for insensitive menuitem (Fix #4)
Merge pull request #5 from Dvad/fix-background-for-insensitive-menuitem

Fix background for insensitive menuitem (Fix #4).
MediterraneanNight: Adjust the colors of tabs of the terminal.

The colors are still not as nice as I wished, but, at least, it is usable
and non-intrusive to my eyes.

MediterraneanNight: Implement murrine-{dark,menubar} to please GTK.

Some of this was shamelessly stolen from some forums, namely:

* https://bbs.archlinux.org/viewtopic.php?pid=1026506#p1026506
* https://forum.xfce.org/viewtopic.php?pid=28950#p28950

I am sure that not everything here is strictly needed (in the sense that I
must be including useless code that should not be here), but I would like to
receive some peer reviews before removing parts of what is here.
