Description:

instances of this class keep all view-style specific information.
The current viewStyle is kept in Views-classvariable called 'StyleSheet'
and is instantiated with 'View defaultStyle:aStyleSymbol', which reads
a stylesheet from a file '<aStyleSymbol>.style' (usually in the 'resources'
directory.

Instance protocol:

 at: aKey

 at: aKey default: default

translate a string; if not present, return default.
Here, two keys are tried, iff the key is of the form 'foo.bar',
'fooBar' is also tried.
This has been added for a smooth migration towards names with a form of
'classname.itemKey' in the stylesheets.
