WAAbstractFileLibrary class>>#asSelector: is still incorrect

[GoogleCodeExporter]

Issue 786 (released in 3.1.1) fixed much of the problem with this method, but 
some issues remain.

What steps will reproduce the problem?
1. WAAbstractFileLibrary asSelector: 'beißen'
2. WAAbstractFileLibrary asSelector: 'all_things'
3. WAAbstractFileLibrary asSelector: 'Berlin'

What is the expected output? What do you see instead?
1. #beien, not #beißen
2. #all_things, not allthings
3. #berlin, not #Berlin

Please use labels and text to provide additional information.

For issue #1., there is an expectation in Smalltalk that #isAlphaNumeric 
answers true ONLY for A..Z or a..z or 0..9, but this is not the case for Pharo 
(at least on Windows) and VA Smalltalk (on Windows, but not on UNIX).

Perhaps we should view issue #1. as a platform issue rather than a Seaside 
issue since Pharo (and VA Smalltalk) are littered with code that makes this bad 
assumption.

We should discuss this issue at Camp Smalltalk (if Joachim Tuchel gets to Brescia in time) or some other time during ESUG. I would like to close it out one way or the other for our next release.
