- Made the CAPTCHA system idiot proof, disabling all the policies still lets an image get created. - We handle the case of a user having GD but no TTF. Thankfully, we have CAPTCHAs that don't need TTF! - Fixed that stupid language string... - Renamed Occlude to Overlap - Shape is now only enabled if TTF support is detected git-svn-id: file:///svn/phpbb/trunk@5985 89ea8834-ac86-4346-8a33-228a782c2dd0
