[mtasc] checking for constructor name

[Ralf Bokelberg]

Every so often my code breaks because my constructor is named different 
from my class. This happens whenever i rename a class but forget to 
rename the constructor. These kind of bug is very hard to find.

Today i had the idea to let mtasc do it, and it actually works quite 
good. All i do is to compare every method starting with an uppercase 
letter to the name of the current class. Whenever they are different, 
mtasc spits out a warning.

You can find the code at http://osflash.org/doku.php?id=mtaschacks

Cheers,
