[mashup-dev] Javascript Function Scheduler Updates

FYI:

While resolving MASHUP-630 (https://wso2.org/jira/browse/MASHUP-630)
reported by Jonathan, I came across a few architectural flows in the
previous javascript function calling mechanism. So I re-wrote it.

The periodic javascript scheduler is now identical to the Javascript
message receiver in functionality as far as executing javascript code is
concerned.

This means that before executing any scheduled javascript function or
code fragment inside a service js file, it will load the relevant script
includes along with the parent service javascript file.

This approach ensures that all the necessary dependencies are in scope
before the scheduled function or block of js code is called. This also
guarantees the availability of a valid rhino context (which was the bug
behind MASHUP-630).

Note: No API changes for setInterval() or clearInterval(), just an
internal architecture upgrade :)

Cheers,
Tyrell
