schematic: mark R15 as no place
...
R15 is pulling VCC_SIM down.
it has probably been added because a load resistor is present in
the FPF2109 datasheet example application, or to not have VCC_SIM
in tri-state.
since we don't read VCC_SIM it is not important to have it in a
defined state.
also the card, phone, or simtrace will provide power to the card
when required (else the card load is high enough to immediately
pull it down).
current flowing from the other card pins back to VCC should not
happen, and if it happens this high value resistor will not have
any effect.
this change has been tested with a real device.
trace and card emulation worked with a Nokia 3310.

updated libraries to KiCad 5
...
the library system changed from KiCad 4 to KiCad 5.
the custom libraries have been re-added to the project, and all
symbol names have been updated.
some symbols are a bit smaller, requiring to add some wires.

any other level is interfering with SAM-BA operation. This fixes
the PA0=GND bug in the previous v1.3 version.

Add R23 (pull-up for !SIM_RST signal)
...
While the SAM7 has an internal pull-up, this is of no use if the bus
switch input is left open and collects noise resulting in bogus nRST
interrupts.
