numbers are separate parser states and there are syntactic octal and hexadecimal constants nowHEADmaster-fmsbw-cimaster

* Instead of every digit being a stack-modifying standalone
  command, there is a single continuous parser state (teco_state_number)
  now - even though it has certain unique characteristics.
  They are consequently documented in the ARITHMETICS AND
  EXPRESSIONS chapter of sciteco(7).
* A number will therefore be rubbed out entirely by CTRL+W,
  including a possible @-modifier.
* (!) Spaces within constants are no longer ignored, but will push
  separate numbers to the stack instead (`1 2 3` pushes 3 numbers).
  The significance of the `,` operator is thus further reduced.
* (!) You can no longer "append" to numbers on the stack as in
  `Qa001` - this was never actually used and caused more confusion.
* (!) Digits outside the current radix are no longer accepted.
  E.g. digit 2 after `2^R`. This feature was also never used.
* (!) Octal constants are supported with leading zeros as in C.
  This works regardless of the current radix set via `8^R` or `^O`.
  It remains to see whether this is actually useful or is rather
  annoying (since every constant beginning with 0 is automatically
  octal, you cannot left-pad arbitrary numbers with 0).
* Hexadecimal constants are supported by at-modifying them as in
  `@0ff`. They must still begin with a digit 0-9 and since A-F are
  valid SciTECO commands, you may need additional spaces to separate
  hexadecimal constants from regular commands as in `@0ff D`.
  During syntax highlighting the number style is extended back to the
  at-sign.
  Note: Hexadecimal constants couldn't have been realized via
  `16^R` (or some shortcut) since that depends on runtime state, but
  we must know during parsing whether symbols A-F are part of the
  number of regular SciTECO commands.
* The new hexadecimal constants are used in the color schemes now.
  Thanks to them, we no longer need workarounds like the "color.rgb"
  macro.
* Since numbers don't have a dedicated terminator character, but any
  letter may terminate it, the number state must behave similar to a
  start state. Consequently, hexadecimal constants will currently be
  auto-case-folded if you enabled this feature.
  I recommend not to write hex constants in upper-case, though.
  Perhaps this should be worked around with a custom process_edit_cmd()
  callback.
* Test suite updated
