Custom scale

[eblanca]

During import, when converting from float to integer values, the caller can now specify a custom floating point value.
Old behavior is kept, and existing application won't break.

I figured out how to use that SFE_BAD_COMMAND_PARAM in case of wrong parameter, maybe that needs fixing...

This seems sane, but the formatting doesn't match the rest of the file and the documentation (in doc/command.html) needs updating.

Oh right, I will fix both.

BTW, in statement
if (psf->float_int_mult && psf->float_max < 0.0)
what's the purpose of that "psf->float_max < 0.0" test ?
I don't get it, maybe it checks for the very first setting of float_max (I see you init it with -1.0) ?
