Client side value caching

[coni2k]

Especially ElementItem - multiplier() method called too many times which makes it pretty slow, improve it. But then how to update the cache, events & properties etc.?

[coni2k]

The values of the the following functions are now stored in local variables;
ResourcePool - resourcepoolrate()
ElementField - indexRting()
ElementItem - multiplier()
ElementCell - numericValue() & numericValueMultiplied()

When there's an update in userService updateX() methods, it raises an event and these functions values are getting updated manually.

It should be applied to more values but good enough at the moment.
Also, instead of raising & handling events with rootScope, it could be done directly by calling setX() methods, so we could control what to update and which order in a better way?

Also "All in One" sample is back but still very slow.
