For easy project setup in CI

Maybe or may not be worth it. Mostly just for learning's sake. Opportunity to refactor as well.

``` /home/travis/build/nnarain/gameboycore/src/gameboycore/src/cpu.cpp:64:20: warning: missing field 'hi' initializer [-Wmissing-field-initializers] : af_{0} ```

Ability to set breakpoints in the debugger.

Pass audio rom tests.

``` CMake Deprecation Warning at src/gameboycore/CMakeLists.txt:7 (cmake_policy): The OLD behavior for policy CMP0054 will be removed from a future version of CMake ```

At some points in the game, it starts to lag. Potentially related to speed mode switch?

Probably something related to a dot-matrix... hm.

``` union Register { struct { #ifdef __LITTLEENDIAN__ uint8_t lo; uint8_t hi; #else uint8_t hi; uint8_t lo; #endif }; uint16_t val; }; ``` Currently, registers are set up as above....
