Currently only implemented for XSSF, as there is no API available for HSSF conditional formatting rule number formats (if it is even in the files).

also includes fixes for
- name shadowing 
- unused deprecated method "getClipRect" in classes extending Graphics2d
- HexDump - replaced intermediate String.format calls with custom padding
- convert testcases to junit4
- closing resources

also tested with an arbitary timezone (PST) and locale (ru)

supresses forbidden apis check for
- LocaleUtil (the only place where Locale.getDefault() and TimeZone.getDefault() should be called)
- Classes using FontMetrics - without the actual text it's difficult to return something sane

Some usage of UTC and Locale.ROOT might be still wrong, e.g. in MapiMessage we don't access the
extended mapi properties, which might contain the timezone

DataFormatter has now a Observable property which need to be observed when custom formats are used
and the Locale changes
