Fixed some warnings in the core project.

motion_emu: fix initialization order

gl_rasterizer: add clipping plane z<=0 defined in PICA

Updated master logo to new logo svg

Fixes a few warnings.

This function is called in clipping, before the pespective divide, and is not used in later rasterization. Thus it doesn't need perspective correction.

hwtested. Current implementation is the correct behavior

gl_shader_gen: simplify and clarify the depth transformation between vertex shader and fragment shader

SwRasterizer/Lighting: implement geometric factor

Refactor MotionEmu into a InputDevice

SwRasterizer/Lighting: implement spot light

* Network: Set and send the game information over enet

Added Callbacks for RoomMember and GetMemberList to Room in preparation for web_services.

dsp_dsp: Remove size assertion in LoadComponent

Fix Spelling/English mistakes

 Services/APT: Use an array to hold data about the 4 possible concurrent applet types (Application, Library, HomeMenu, System)

gl_shader_gen: don't call SampleTexture when bump map is not used

Travis: Use Docker to build for Linux

Implement correct folder structure for CI builds

Fix some spelling mistakes

HID: zero unused PadState bits
