Templating e-mails

As for now e-mail are send in a single laguage prom plain string templates. It's inconvinient as there is no localization, we can't include links there (as deployment root is unknown) and so on.
We need to alter templating in e-mail's by using some standard view framework. JSP is not the case since it requres tomcat to be preprocessed and thus cannot be tested on it's own. Probably velocity mail templates will do the trick, however it's still questionable if we can render them in usual web context.
