1. removed zl, zr and c-stick from HID::PadState. They are handled by IR, not HID
2. removed button handling in EmuWindow
3. removed key_map
4. cleanup #include

Timer: restore missing signaled=true from #2421

IR: separate functions of each port to their own files

Corrects a few issues with regards to Doxygen documentation, for example:

- Incorrect parameter referencing.
- Missing @param tags.
- Typos in @param tags.

and a few minor other issues.

Replace built-in Profiler with indicators in status bar

Now based on std::chrono, and also works in terms of emulated time
instead of frames, so we can in the future frame-limit even when the
display is disabled, etc.

The frame limiter can also be enabled along with v-sync now, which
should be useful for those with displays running at more than 60 Hz.

More ergonomic to use and will be required for upcoming changes.

They're not very important and this makes the display changes less
often, making it less distracting.

Change travis tar command to specify compression format

macOS uses bsdtar which doesn't have the -a flag which determines
compression based on file extension.

APT: implemented Wrap and Unwrap

Timers: Immediately signal the timer if it was started with an initial value of 0

Use gzip instead of lzma on macOS releases

* Added a refresh game directory option to the file menu

* Make the game list watcher recursive and have it start watching from the initial load

* Rework game list watcher to be thread safe

* Fix code style issues

Gui: Change title bar to include build name

Uses tar -a flag to determine compression algorithm based off file extension (so linux will continue to use xz and macOS can use gzip)
