5eef25f86b Updates SW1 location and pin 
Previous, SW1 was too close to RST, making it difficult to press one
without pressing another. After changing its position, it was more
convenient to route SW1 to pin 10 on U1 - That's P0.30/AIN6 both on
nRF52840 (C) and nRF52833 (E) modules.

7f652ce75d BIG YIKES - Fix wrong symbol/footprint for MMBT3906 (Q1) 
I previously used a basic 2N3906 and then changed its footprint to
SOT-23. This led to the wrong pin assignment.
This commit fixes it by using the correct symbol and footprint for it.

Note that the PCB layout still needs fixing.

123149d3d2 Some initial hardware changes for the 2.0.0 revision 
- Simplified the fast discharge circuit to use a single PNP BJT instead
of two NPN BJTs
- Swapped nRF52 module's footprint for one with larger pads
- Added a user button tied to P0.12 (same as Button 2 from [nrf52840_dk](https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf52840_dk%2FUG%2Fdk%2Fhw_buttons_leds.html))
- Added a reset switch

These are only schematic changes - PCB layout is stale and needs to be
recreated.

e7f7f96797 Moves KiCad project file to KiCad 6 
Moved the Q4 photodiode footprint dot (representing the collector) so
it's more clearly visible. Hopefully it will help addressing the
recurring confusion about Q4's orientation (#3, #42).

The C_para is just a virtual capacitor, formed by the PCB traces, and
should not have an entry in the BOM file.

d3ed9a3311 Fixes Q4 (phototransistor footprint) 
It was not marked as SMT, so the exported position file didn't include
it.

This also adds ~15mm to the length of the board. This extra clearance
should help prevent shorts when watering plants.
