LPC gui theming (replaced windows through scrolls)
Fixed gender to male only
Implemented scaling in OpenGL mode

The screen will be scaled up as much as possible, while keeping a
minimum 'virtual' resolution of 640x360.
Removed debug output
Small optimization in OpenGL clip area code

I added mScale later and forgot to make the clip area code use it.
Implemented client scaling in SDL mode
Added lpc window theme image to CMakeLists

Enabled specials window by default
Fill the window also in software rendering mode

Mouse handling is broken when the game only fills a subset of the screen,
and this doesn't look very nice either. Do the same as done in OpenGL
mode for now.
Fixed pixel alignment drawing glitches in OpenGL mode

At some window sizes, lines would flicker in between the tiles. This
happened when the window size was not dividable by the scaling factor.

Fixed by setting a slightly smaller viewport in this case (which will
hopefully not cause other issues).
Removed options to configure particle  and ambient effects

As discussed on IRC we agreed to remove the particle and ambients effects
options. They are important for the game play and should stay enabled.

Also moved the remaining options right to the resolution selection since there
is enough space for them now.

Change is tested.

Themed the remaining ui for the lpc
Replaced font with DejaVu Serif Condensed

Looks nicer in the game in my opinion.
Corrected the minimum height shown in the video options

Actually for me it doesn't list 640x360 anyway, but it might for some
people I guess.
Fixed UI layout after changing resolution in Setup dialog

It was doing the relayout using the unscaled screen dimensions.
Reduced the height of the Setup window

Also removed all the hardcoded sizes of the various setup tabs. Instead,
support for dynamically adjusting layout was added to the Container
class.

Various other places were also adapted to use the new layout support in
Container.
Fixed the dimensions of the popup/tooltip
Removed UI to manually increase skills
Fixed height of item popup that shows no item
Removed player box from the equipment window
