#29 New variable / parsing engine

[nathan hruby]

The current 0.65 variable situation is much better than
previous versions. All the variables are in one array
and it's very neat.

Currently phpslash does little checking on user input
to chnage variables (skin, lanuage, etc..) on the fly
and each subsction is responsible for finding and
dealing with the variables they need.

Would like a set function to suck in GET and POST
variable chnages and sanely inport them into the $PSL
array with respect to global and user pref's all the
while checking the input to make sure nothin foul is
afoot. this would be a much better and more OO way of
dealing with things.

Even better would be to have the ability to allow
modules to tell the variable parser what they need, so
superflous info is dropped and psl never sees it.
