Squeak needs version of WAInspector

[timrowledge]

Whilst trying to follow the HPI seaside tutorial (so many problems...) I used the halo to inspect some component or other and discovered that the WAInspector current isWAPharoInspector, which implements #evaluate in a manner that cannot work for Squeak.

I'm pretty sure it should be

evaluate
^self object class compilerClass new
evaluate: input for: self object

... but not certain yet. Also not sure where one would put any WASqueaInspector select in the package loading process.

Simple implementation follwed by manual WAPharoInspector unload & WASqueakInspector select seems to make the UI work ok.
