cf1bc4fad4 Fix Pop() implementation in src/sim65/paravirt.c (fixes #1625) 
The Pop() function was not handling stack pointer wrap around correctly.

Also, change the simulated RTS implementation in ParaVirtHooks() to
explicitly sequence the two Pop() calls in the correct order.

fb0d09a277 Changed sim65's internal error codes from 9-bit values to 7-bit values. 
Some shells truncate process return codes to 8 bits.  And, the eigth bit often is used to show that a signal stopped the process.

6efb71bea7 Rearranged paravirt function vector. 
- exit right below 6502 vectors.
- keep exit addr stable as it may be called from asm.

Quotations that are embraced by tick marks now look better, in most fonts.

d602572bbe Fix permissions for files created by sim65. 
Files created by my programs running under sim65 had really weird permissions:
--w-r--r-x  1 ppelleti  staff  19 Aug 16 23:22 json.test.print.tmp

So, for example, my program running under sim65 was not able to read
the file it had just written.

This is because the third argument to open (mode) was not being
specified in paravirt.c, so it was just picking up random crud off the
stack to use as the mode.

I added a mode of 0666, and now my program runs correctly.

dce5783dc9 Fixed the simulations of the stack pointer and the "break" and decimal-mode flags. 
* The pointer wraps around the stack page.
* The break flag exists on only the stack, and only after an interrupt.
* 65C02 interrupts clear the decimal-mode flag.

50c4fd1c4c Improve MinGW support. 
- Code specific to Windows was #ifdef'ed with _MSC_VER so it wasn't included with MinGW. So _MSC_VER is replaced with _WIN32.
- MinGW doesn't support _get_pgmptr() so it is necessary to directly call the Win32 function GetModuleFileName(). This implies including windows.h which in turn causes a name clash with the Win32 function SearchPath(). So the cc65 type SearchPath is renamed to SearchPaths.
