easy listening

..Needed a way to safely tryout windows buildchains like TDMGCC without interfering with the already installed ones.
Found a way in a sandbox Path Option with myScites Tools as an answer. So just set sandbox=1 and test safely ;)
..While i was working there anyway - updated Uncrustify and added Ctags support. (Credits: https://github.com/mingfunwong)
... Finally applied the (update) portable Patch to SciTEGTK.cxx.
..While movin further with the linux64 build, im currently working on a win64 target too. What a luck im a fan of collecting sources- this way i can remake all required addon modules for 64bit.
btw... - who likes to deal with neither heap, stack and picky compilers these days anymore.....
meanwhile .. switched to not use getenv directly. worked out of the box. HRMPF:
