New captcha images and fonts

[thorn]

Hello,

the captchas from 2.7 are somewhat dark and heavy -- so i made these lightweight ones.
Just unzip and copy the content from captcha/ to wb/include/captcha/

thorn.

EDIT: to remove the old, dark backgrounds, go to wb/include/captcha/backgrounds/
and rename these files:
bg_01a.png
bg_02a.png
bg_03a.png
bg_04a.png
to e.g.
bg_01a.png_
bg_02a.png_
...

EDIT2: the used font-files are reduced FreeFonts from http://www.gnu.org/software/freefont/ (GLP)

Hello Thorn,

thanks for this goodies. Think we should add the new captchas to the WB core files.
