Hide scripts from end-user

[Lwmte]

Currently we keep scripts in a raw text files inside Scripts folder. This makes it extremely easy for end-users to randomly edit those files. For now, when TEN is in beta stage, it's okay, but for future, it may be necessary to implement a way to "hide" scripts from player, so he won't mess with them.

I propose simply packing all scripts into single zlib archive (we can even call it SCRIPT.DAT) and unpack it into memory on start, and access scripts solely from memory. For debug purposes, we may keep direct script loading from text files, so TEN would search for Scripts folder first, and load files from it, and if such file is not found, SCRIPT.DAT is used (or vice versa).
