* Improved pin manager, ethernet config
* Ethernet is configured prior even to LED pins
* Pin Manager allocation / deallocation functions
now take an "ownership" tag parameter, helping
avoid accidentally free'ing pins that were allocated
by other code
* Pin Manager now has ability to allocate multiple
pins at once; Simplifies error handling
* Fix operator precedence error
Bitwise AND has lower precedence than the
relational "greater than" operator.
* PinManager update for some user modules
* don't build everything...
* Final step to reduce RAM overhead
* update comment
* remove macros
* Remove leftover allocated
* Init ethernet after settings saved
