[axis2] QNames / Strings

[Glen Daniels]

1) A lot of places we're currently using QNames (handler names, for 
instance) might be better off using just Strings.

2) There are a ton of "new QName(STRING_CONSTANT)"s speckled about the 
code.  When we really need a QName constant, we should be making a QName 
constant and using that instead of new-ing up an Object each time we run 
through.
