Added CPC machines support to ZSF snapshots
Added tape to wav converter (tap, tzx, o, p to wav)
Improved CPU usage in TBBlue:
-Use 4% less cpu time (in my machine) when only ULA and/or Tiles enabled
-Use 1% less cpu time (in my machine) when all layers enabled
Improved ZRCP:
-commands smartload and snapshot-load are more intelligent now
-running in verbose or limit mode, or cpu-step command, can now update the display inmediately (having real video setting on)
-added commands: get-cpu-frequency, get-cpu-turbo-speed, get-tstates, get-tstates-partial, reset-tstates-partial
Improved vu-meters: high volumes are shown in red

Improved file selector:
*now it remembers the last files used
*Windows: now you can use up to 20000 files in the same directory

Fixed triggering "opcode" condition breakpoint
Fixed emulating Inves interrupt bug
Version 7.1. 24 September 2018 - 5th Anniversary edition
