Remove class weapon restrictions on ME2

I agree it would be nice.  There's a slight problem with doing it like ME1.  With the addition of new weapon types plus heavy weapons, I don't think that the UI can support every one of them.  Unless I've counted wrong, one has to be omitted from the list, or the last one in the list (heavy weapons) won't be accessible.

In my own edits, I've given more weapons to the classes, but I had to pick and choose which one to omit from each class based on my interpretation of what each class should be able to do.  Bioware probably didn't want to deal with the controversy of whichever choice they made.  At least that's my assumption -- might be wrong.
