added short reqmgr templates for Dev/DMWM tests; still missing taskchain

As discussed with Seangchan, I'm pushing these templates to be used by Devs for quickly testing their bugfixes/features. It includes all types of requests but TaskChain.
I have also included a summary text file, so one can use to perform some quick checks about the templates and where to run them.
Please let me know if:
 a) you are not happy with the directory naming
 a.1.) in the near future I'll move the others to "requests/Integration" and get rid of the unused ones.
 b) if you find any problems with them. After moving them from one machine to another their formatting got a bit messy
They were all tested already (well, before fixing the indentation :))
Thanks, Alan.
