Please change variable names - add vbseo in front of them

I used a program that I havn't touched for a while and it wouldn't work. After a while I realised that the program was being messed up with variables that were the same as what vbseo was using. In particluar, the $url in that instance.

I have since renamed the variable in my program, but it would make better sense if all your variables were more unique to your program. ie for the $url variable, that it was named say $vbseo_url.
