[BP 7.1.4] - FunctionOverload parser resulting in false positives

functionOverload regex results in false positives where it incorrectly flags function names having reserved function names as their prefix. Example:

function createTimerBlah(a,b) {

return a+b

}

Here, the regex finds "function createTimer" and falsely determines this to be an overload of the createTimer reserved function.

Similar examples include:

function logger() {}
