Move acceptable character set determination to form submission time, rather thanat box tree creation time.
Use UTF-8 encoding, if specified, else use first specified encoding.
Improve use of utf8_to_enc - falling back to document encoding then 8859-1 where appropriate.

Split out UTF-8 handling functions.
Submit URL-encoded forms in sensible encoding:
* First entry in accept-charset list, if present
* Document encoding, otherwise
We may want to explicitly look for UTF-8, to save converting.
Convert cnv_str_local_enc/cnv_local_enc_str to use iconv (they're now veneers for utf8_[to/from]_enc).
Provide mechanism for looking up local system charset (derived from system alphabet, under RISC OS)

Update and simplify textarea code. Now uses BOX_BR instead of more than one inline container. Prepare for use of UTF-8 in textareas and inputs.

Improve keypress handling in form text boxes.
Note: Not yet implemented for textareas as these need more work anyway.
