ESP32 added, with some minor bugfixes

Changes:

• Added sample configuration for an esp32 based build.
• Split out the config to make easier to modify.
• Can now customize name (not auto reflected in label yet).
• First time will show not show epoch time, rather fishfeeder epoch.
• Ordered the webinterface (workaround until esphome/feature-requests#1774 merges).
• Split out !secrets.

Bugs fixed:

• QR code is now vector image on label and box, before it was linked as a rasterized image.
• Consistent naming FishFeeder, and updated links reflecting this change.
• Fixed bug where last update time would show old value in web interface until first feed moment.
• Can no longer set end of day feed time before the start of day (although scheduler is happy to comply).
