* a number of minor fixes leading to an increase of 570% to 588% on
pongf.
* admittedly micro optimization.
* Includes some comments why certain decisions have been taken.
- The write protection bit was inverted, with that change you can write into IMD files without error.
- The ramcard was broken, it should only respond to addresses below 0x8000, now the option -exp ramcard works and boots up correctly
- Correct mnemonics for CLC, CLV, CLZ and CLN
- Add MFPT mnemonic
- Rename JSR/RTS short forms to CALL and RETURN
- Eliminate alternate PUSH and POP mnemonics
- Add notes on instructions not implemented on T-11
* length reports the number of character codes in the string
* size reports the size in memory units
* Reminder: Set PSTRING_USE_STD_STRING to 1 in pstring.h and get
native std::string
* pstrings are compatible to std::string but only support a limited
subset of functionality.
* By default (always like this) utf8 is supported and thus length
reports the number of multi-byte characters.
* Document that for performance reasons pushes to queue are
allowed even if they may not change state and are filtered
out during process.
* Provide alternative code path. This is currently not used.

35 in 1 Super Twins [David Haywood, Sean Riddle]
Vs. Maxx 17-in-1 [David Haywood, Sean Riddle]
made use of the code that was already partially present in the NES PPU code to handle emphasis modes, used to highlight tally bars etc. in 'nes rampart', apply a red tint to 'fds bublbobl' and dim the screen in a number of other games.
fixed a number of issues with VT palette modes that was causing black screens in many games, allowing them to be promoted
added a timing kludge for interrupts in the NES Frogger titles, until timings are better overall,makes playfield stable here and in a number of other places so that other things can be improved
note "Vs. Maxx 17-in-1" was added as NOT WORKING in this same cycle so if this gets merged before freeze they'll need to be moved to the 'new working' section.
This is a checkpoint, further code improvements and refactors will come later.
