Summary:  using regex for validating input

Original Submission:  Regex for parsing the multitree config file



pros and cons:

 + better validation of input

 + more precise error reports

 + filenames can be quoted now and might contain spaces then  

 - much slower (probably one can optimize the regex to gain speed)



further ideas:

 * envvar expansion

 * escaping rules for spaces and special chars in strings



Please review the idea and think about applying it on serveral areas in tla (i 
plan to add support for filenames with spaces throughout tla with this)



the structured_regex.h file should live somewhere else, maybe in hackerlab, but 
its still quite immature.



In all this works so far but its only a proof of concept and need to be judged 
if we want to use it.
