- Create `Include/` folder for all main projects
- Fix some issues here and there (found while moving things)
- All includes are now in `Tactility/` subfolder and must be included with that prefix. This fixes issues with clashing POSIX headers (e.g. `<semaphore.h>` versus Tactility's `Semaphore.h`)
- Various improvements to Thread and Timer:
- Remove "mark as static" option as it is unused
- Implemented core pinning for ESP32 platforms
- Use `TickType_t` consistently (instead of `uint32_t`)
- Use `enum class` instead of `enum`
- Fix for `flash.sh` not working when using `pip` to install `esptool`
## Time & Date
- Added time to statusbar widget
- Added Time & Date Settings app
- Added TimeZone app for selecting TimeZone
- Added `tt::time` namespace with timezone code
## Other changes
- Added `SystemEvent` to publish/subscribe to system wide (e.g. for init code, but also for time settings changes)
- Changed the way the statusbar widget works: now there's only 1 that gets shown/hidden, instead of 1 instance per app instance.
- Moved `lowercase()` function to new namespace: `tt::string`
- Increased T-Deck flash & PSRAM SPI frequencies to 120 MHz (from 80 MHz)
- Temporary work-around (+ TODO item) for LVGL stack size (issue with WiFi app)
- Suppress T-Deck keystroke debugging to debug level (privacy issue)
- Improved SDL dependency wiring in various `CMakeLists.txt`
- `Loader` service had some variables renamed to the newer C++ style (from previous C style)
Remove dependencies M5Unified and M5GFX because:
- Sometimes the release doesn't even compile
- The amount of functions is too close to the limit (I recently had to remove some code/dependency to be able to make a build at all)
- Graphics performance issue since last update
- Touch screen performance issues (not perfect yet, but better)
- Compatibility issues with Tactility SPI/I2C versus M5Unified/M5GFX variants.
