bugfix multiple test annotations and string()

customized tags

support multiple methods annotations and a single path mapped to multiple functions

increase performance, fix call for fallback congfig

by using a less strict, but much faster method to test if a module is 
prepared with RESTXQ annotations, we increase the performance by factor

"%rest:"

add a parameter to trigger re-registration of REST functions
