BStringView: Add scripting support. Fixes #9823

Browse Source 
Configure BStringView to respond to messages to get and set Text and Alignment
properties. Fill out ResolveSpecifier() and GetSupportedSuites accordingly.

BeOS R5 did not provide any additional scripting support for BStringView so
this goes above and beyond what BeOS R5 did, but, doesn't break backwards
compatability.
