Added CMake build.

Code changes to support Linux.
Updated documentation & README.md, which were sorely out of date.
Updated copyrights. *yawn*

+### How do I build it? ###
+
+Dependencies for building are CMake 3.x and a C++11 compliant compiler,
+all other dependencies are in-tree so you should be able to build with:
+```bash
+mkdir build && cd build
+cmake ..
+make
+```
+
+Optionally, to make it convenient for my dkp projects:
+```bash
+sudo cp tmx2gba $DEVKITPRO/tools/bin/tmx2gba
+```
 
 ### Todo list ###
 * Add support for multi-SBB prepared charmaps.
-* Test on & write Makefile for Linux.
+* Test CMakeLists for Windows compatibility.
-* Export to C/ASM with width/height info.
 * Check if this works for NDS as well.
-* Implement some kind of grit-style parameters file for easy integration into buildscripts.
-* Revamp command line arguments.
 * Compression support.
-* Refactor & Fix bugs.
+* Prehaps use GNU style getopt_long?
+* Refactor & Fix bugs. *(duh)*
