Acqua with Dropshadows - l3m flavoured

This is a modification of the kwinacquamod with dropshadows...

i added the goodies from my former kwinacqua mod:

- correct buttons and button placements
- grey inactive titlebars

and i added these configuration options:

- shadowed titlebar text is now optional
- you can choose between
-- no right button
-- a menu button
-- a context-help button

(just look at screenshot 1 :) )

I also changed the name of the lib, so you can install mine and another kwinacqua without any problems....

Installing:

$ ./configure [ options ]
$ make
# make install

for debian users, there's an install script which sets all the correct configure options, so it's only:
$ ./build-debian.sh
# make install

Thanks to the apple designers and all the people who worked on this theme:
- rik hemsley
- m.j.soto
- thormedia
- noonespecial
- david sansome
- l3m ( me )

New configuration option:
- "borderless" mode
( check screenshot 2 )

New configuration option:
- "light inactive style", inactive title bar is not darkened
...done upon request from here, but it looks so cool, it's now default :)
you can see the effect on screenshot 3 - doesn't look like much, but try it out! You'll be surprised!

Bugfix:
- icon doesn't get drawn behind buttons if the window-width is too small
