Bugfix: Inonsistent Brew & Steam switch behaviours #413 #414

Debounce on Brew trigger. Steam trigger code duplication disabled debounce.  Debounce times to 20ms.
Added variable brewSwitchLongPress and set to 500ms.
Rename BREWSWITCHDELAY to SHOTTIMERDISPLAYDELAY, adapt comments to fit to functionality.
Rename brewSwitchLongPress -> brewTriggerLongPress and
lastButtonStateBrew -> lastStateBrewTrigger
clean brewvoid
rename a lot of variables to naming scheme
rename var steam and power trigger

more rename variables
