add error handling for remote functions

[GoogleCodeExporter]

we will have mutliple forms and update methods.
returning a  string-value containing the error if any has occured is bad
cause the error-message would be hardcoded into the application.

error-messages must be:
multi-language (=> must be linked into a language field)
should be template (=> cause you have to replace sometimes the arguments of
an error message to make it usefull... for example:
*the name "swagner" has already been taken* instead of *the name has
already been taken* 

To make it running there must be templates stored into the database which
must be loaded through "velocity" and replaced with arguments and then
returned to the client.

missing methods:
getErrorById()

It should return an error-Object with an header and a message (maybe
possibility to resume)
