Font file not found

Included is a patch to Captcha Numbers V2 to allow fonts (with paths) to be specified in the constructor. I needed this on a Debian Linux system to get to the Arial font which is provided by MicroSoft and installed in a sub-directory of /usr/share/fonts/truetype (which is where GD is looking for them).

Thanks for the effort to produce this class.

Strange what you are saying: I have tried it on Debian Sarge, with an Freetype font (which was mentioned in the readme file) outside the htdocs-dir (one dir upper), the virtualhost is "open_basedir"-ed (so it can't include fonts from the filesystem), and it's working perfectly (I have just edit the class to specify the path of the font, which is also outside the htdocs-dir).
(Also I had to install the php4-gd package which was not installed by default.)

BTW: Thanks for this class ! (And greetings from Hungary)

Modified class ctor to allow setting fonts folder. If folder is set in ctor then fonts are loaded from this folder.
