Fixed dependency notice on itself

The function states a dependency on itself. This function even doesn't depend on aggregation_info() so I removed the comment line.

Dependency on itself
Avoid eval in call_user_method funcs, allow PHP-alternative argument structure, actually call method on supplied object
Support specification of object inside array as global string as per PHP (still no eval, but string approach only works on functions directly on window object)
urldecode functions: Tolerate poorly-formed escape sequences as per PHP (thanks for the input lovio!)
JSLint date(), including localizing accidental global 'i' var.
Apply fix of Theriault, input by Haravikk, per https://github.com/kvz/phpjs/issues/76
strtotime() clean-up incl. mistaken global, handle "next mon(day|\.)" issue per https://github.com/kvz/phpjs/issues/99
clean-up, allow as in PHP, array with object (optionally as string) as argument and callback (optionally as string) (per issue 31 at https://github.com/kvz/phpjs/issues/31 )
There are only two parameters for function _pad. Thus I removed this obligate parameter.

functions/datetime/date.js bugfix
I experienced problems for iPad2 (native browser) using the former implementation, if n is no object and has no toString()-Method. So I replaced with String()

Additionally I feel it is better to avoid recursion here (which causes multiple calls of String-Constructor/toString()-Method) is better.

bugfix for similar_text.js

Fixing similar_text.js based on findings on http://stackoverflow.com/questions/14136349/how-does-similar-text-work

Basically, in some cases the algorithm is not implemented correctly. It shouldn't produce the same result when swapping the input words but it seems to do so.
