Got rid of problematic attempts to save status register after function calls. If you really need it (for instance for if_XX instructions) it's probably better to use a short asmsub wrapper.
...
For function calls, register saves go via stack (to allow nested saves) for simpler cases, registers are saved in a local variable.
Fixed too agressive removal of sta-lda sequence if the lda is followed by a branching instruction.
Insert missing cmp #0 after functioncall if the value of the A register is needed in a comparison expression (could otherwise test wrong status flag)

cx16 virtual registers R0-R15 also available on C64 target (although in a different location in memory)

removed the automatic system reset at program exit, this did't work with the new init code

reworked program init logic so that it is included as the first thing inside main.start itself, to allow better stand alone asm

auto select correct library to import based on target, instead of having c64- and cx16- prefix variants
...
some programs are now 100% source compatible between C64 and Cx16 targets!
import libraries have been rena;med
