not work if the main language encoding is latin1 and a character

iconv refuses to convert such a character to latin1, although it
exists in latin1 (it wants to attach it to a base character).

codepoint > 255.
I decided that this is no file format change: We already had the change to
format 249 that allowed unicode in .lyx files. The output to .tex of
non-ascii characters is now different than before (even for those that were
supported previously, e.g. german umlauts in latin1), but this is only
relevant if people referenced a label in ERT. Since we cannot detect this
anyway we don't need a file format change.

Known problems:
- No space is output after a \hfill. I probably broke this with the
InsetCommand patch. I'll have a look later.
- Although the encoding is now UTF8 the arguments of the inputenc package
are still the old ones, so LaTeX will not run.
- Labels and references with non-ASCII characters are broken. This needs to
be fixed in lyx::support::escape(), but this is a file format change.
- Something seems to be wrong with index entries, but this is probably also
due to the InsetCommand changes.
Have fun!
