EBT - ESPboy tracker

EBT has been updated to v1.1. It is easier to use on a PC now, as it uses a different control layout, and supports PC keyboard. A custom made keyboard technically can be also attached to the device, and it is possible to support it, which opens up interesting possibilities too.

Changes are:

- Play option removed from SONG screen
- Name and author fields are added to the song file, can be set from the SONG screen
- Squeeze function added to optimize song data
- Some waveforms tuned up to match the original wtbeep, to allow easy conversion between two
- Stereo panning reworked a bit, allowing 9 positions left-to-right instead of 3
- Default panning settings are added
- An option to swap the LFT/RGT buttons
- A crash course section added into the manual
- Two cursor colors swapped to make it more visible with blinking off
- Play/Stop info line is only shown while the RGT button is held down
- 32 extra waveforms added, including various noise and modulation effects
- Sound synthesizer and music player separated into two independent entities
- A standalone player code that stores data in the program memory

Hardware-specific:

- LovyanGFX display library supported
- 2.0 inch TFT display support (ST7789V) for a custom built EBTboy

SDL build specific:

- Irrelevant config options such as sound output device are not displayed
- 128x128 and 240x340 modes support, with 8x8 and 15x16 fonts
- Main control keys are remapped
- Direct keyboard support added, for entering numbers, letters, and better navigation

I haven't tried it with Linux just yet, but it should be trivial, as it does not use any third-party components besides SDL2. So this untested makefile may work. Please try it if it is not too much hassle. I'll get to it eventually, but I don't have an easy to access Linux environment at the moment.

I also have a report it works just fine with WINE.

Edit: Actually, attempted to make it work. It compiles and starts, although it crashes on me right away, but so does 1tracker in the same install (lubuntu in VirtualBox). I uploaded the WIP in place of the release, you may try it out.

Edit: fixed it up some more, now it fully works under Linux.

You need to have /fonts/ and /data/ in the same directory with the executable, if they're not found, it won't be able to load fonts and will close. Missing ebt.cfg is just a warning, it will report it and continue to work. When you'll change something in the CONF for first time, it'll create the config file and stop giving this warning.

Wow, sounds sick!

Not too sure about the number keys, maybe a specific scenario to reproduce the issue? Does it happens all around, or at a particular screen such as order or pattern editor?

Promoted the current version to v1.11 with minor changes and fixes, as I have a number of bigger ones in the works.
