  1. revC2: Bigger footprint bulk cap and reset button. 

    Details:
* Replaced the bulk capacitance polymer capacitor with a larger
footprint version as the 6.3mm footprint is more common.
* Added a reset button that instantly resets the cirucuit. Meant also as
emergency stop. Reset will result in cutting power to the target instantly.
  * To enable reset we replaced the power supervisor chip with one that
  has a reset pin.
  * As the pullup current of the supervisor chip reset line is very low,
  we have added a capacitor parallel to the tact switch, to improve
  "wetting current" and break down contact oxides.
  * To make space for the reset button I decided to replace the SO8
  EEPROMs with TSSOP-8 packaged versions.
* While already moving things arouond I increased the gaps between the
status LEDs from 1.75mm to round 2.00mm. This should make lightpiping
easier when we design a case for the glasgow.
