Fixing Moodle 2.3 compatiblity issues

I know you are not the main developer, but I am using the refactored repo you put out. I just installed block and found some errors and fixed them. Did you try contacting the original developer to accept your refactoring of his repo so it is easier to clone?

Changelog:
* removed call to deprecated "require_js" function
* fixed lines that were causing PHP strict standards errors of "Creating default object from empty value"
* fixed type in README
