Support bright background colors:
- for PETSCII, this is automatic and you don't lose blink, but you do lose colored foreground when enabling a bright background ("reverse video") - for ANSI, this mode is typically referred to as "iCE colors" and disables blinking-text support - Ctrl-AE (^AE) is the new attribute code to enable bright-background (will have no effect on ANSI terminals that are not iCE color enabled) "E" is now valid in the ctrl/attr.cfg file and string values for JS console.attributes assignments, as well - Ctrl-AI (^AI) - blink - now does nothing for ANSI/ICE color terminals (blinking is not supported in combination with bright-background) - Using a new/non-standard CGA attribute bit-flag to indicate the selection of bright-background colors (BG_BRIGHT, bit 10), separate from BLINK. This change required all/most char/uchar attribute representations to be converted to int/uint. New text.dat strings: - PetTerminalDetected (renamed from PetTermDetected) - PetTerminalQ - TerminalAutoDetect - TerminalColumns - TerminalRows - TerminalMonochrome - TerminalColor - TerminalIceColor - IceColorTerminalQ This also moved the MsgCarbonCopyList definition to the end of the file for now. PETSCII reverse-video attribute fix: When a CR is sent to the terminal, the reverse-video attibute is auto-disabled so update our "current attribute" (curatr) value to match the remote. Support new printfile/putmsg mode flag: P_WRAP to force an ungraceful line-wrap (splitting) to the specified column width. If no column width is specified (0), then this mode will force an ungraceful wrap before the last terminal column where some terminals *may* auto-wrap. JS console.printfile() and printtail() methods now support an optional "orig_columns" argument, similar to console.putmsg(). Must specify P_WORDWRAP or P_WRAP for this argument to have any effect. Much improved terminal-type selection/configuration in the user defaults menu and abort (^C) at any of the yes/no prompts is now detected/handled much better (to answers to the prompted questions are not saved to the user settings).
