weaponpool.txt dbid sorting tool 1.0.0

Sorts weaponpool.txt by dbid parameter.

Since it's a pretty simple task, I had two pathway opportunities: Either program from scratch or re-use all the code from previous tools. Given my current lack of time, I've decided for the latter, resulting in the tool being completely over-engineered. On the other hand, with some little tweaks this tool has the potential to become a universal file sorting tool for all Sacred 2 .txt files supported by my other tools because of that.

One final thing: it only sorts and writes the defines, any commentary at the start or end of weaponpool.txt or inbetween the defines will be lost. Commentary inbetween the start and end of a define however works fine and will not be lost.
