Propose a focusin action on jquery.priceformat.js

[ahmfarisi]

I propose to add a focusin action on jquery.priceformat.js, exactly on bind the actions section

//bind the actions
obj.bind('keydown.price_format', key_check);
obj.bind('keyup.price_format', price_it);
obj.bind('focusout.price_format', price_it);
obj.bind('focusin.price_format', price_it);

This is simple, but useful when the project made a calculation and the result of calculation will be automatically put inside a textbox.

Example:
By adding the focusin action like what I proposed, the project just need to add a

document.getElementById("anyIDforResultTextBox").focus()

After that, the result of calculation will be following the needed priceformat on the textbox.
