cintoo Messages Alpha 2 released

I've released nother alpha, which looks quite final, so the next one will be a beta version.

Changes since the last version:
- Added support for hierarchies, if a key is not found in one context (e.g. my.package) 
  Messages now looks in the parent context (e.g. my)
- Added support for language hierarchies,if a key is not found in one language (de_de) then 
  Messages looks in the less specific language (de)
- Added much more unit tests (more than 90% coverage, thanks cenqua :-)
- Added unintrusive method names. _() now mirrors the format() methods

I wish you less i18n problems with the usage of Messages
