Closes #215

Add more services and general fixes

in the service's headers

Remove trailing spaces from the entire project

Add static to some variables

Update gitignore to exclude project/editor files

Stretch emulation output to render window and be display density independent

Fix documentation of parameters

directory_sdmc: Fix a signed/unsigned mismatch comparison

system: Get rid of an unnecessary enum typedef

Remove extraneous semicolons

GLFW provides no proper support for this, hence we just allow any window size to be used.

Implementing this function currently is not critical, as we don't perform any configuration changes, yet.

However, the interface is a good starting point for adding this functionality.

The window title is none of the emulation core's business. The GUI code is free to put whatever it wants there.
Providing properly thread-safe window title getters and setters is a mess anyway.

The view is scaled to be as large as possible, without changing the aspect, within the bounds of the window.
On "retina" displays, or other displays where window units != pixels, the view should no longer draw incorrectly.

Replace asserts with _dbg_assert_.

core: Mark some hle functions as static

These functions are not referred to by their linkage name outside of the translation unit, so they can be marked as static.

FileSys: Updates backend code to use FileSys::Path and fixes binary path types.
