* Implemented several esc[m codes

* Added commands for setting default foreground and background

* Added control codes for high intensity colors

* Update gfx.c

Change the arithmetic for background intense color to correct a small color selection bug

* Updated binaries

* add 1m,2m,22m and 27m for legacy intensity support (#53)

* add 1m,2m,22m and 27m for legacy intensity support

added control codes to control color intensity, for 4 byte color selection in programs that use the legacy color selection scheme 1,2 and 22 (for programs that do not support 90m-107m).  fixed a bug in 7m that would cause older code to occasionally produce output were reverse did not work correctly when calling 7m or 27m when it was not needed (when the state was already swapped). this was done by adding a 'reverse' variable to ctx so that the terminal can keep track of color swaps for the state of the reverse text. the above fixes produce proper output with gorilla.com under CP/M.

* Update docs and bin folder

compiled the patched version

* Update gfx.c

code formatting change

* Improved formatting and fixes compile on Linux
