ti/lcd: allow for fonts smaller than 5 pixels
...
That's a lot of code for such a small change, but there's a big difference
between 5 pixels and 4 pixels: 4 pixels requires compositing.

ti/kbd: improve debouncing
...
Previously, on real hardware (emulator behaved fine), we would routinely
get repeat keys unless pressing the button very fast. This commit solves that.

ti/kbd: make Alpha and 2nd toggle
...
Previously, when being in A-Lock mode, activating Alpha wouldn't make
us go temporarily in digit mode, as is expected.

recipes/ti84: first step
...
This was mostly lifted from my "tihello" example, but it required significant
adjustments.
This commit also introduces a font management system. A lot of fonts are
available online, but sources aren't always clear so to avoid copyright
landmines, I re-created my first 5x7 font from scratch.
As it is now, this resulting ROM gets "Collapse OS>" to be displayed on the
LCD screen. Much work still left to do.
