Add workaround for lack of A_ITALIC in old ncurses 

A_BLINK has probably always existed, but there's no good reason to
ever use it, so make it do italics instead. Normally all attributes
are set by a single set_attributes string if it's set, so clear it
to force ncurses to use the reassigned enter_blink_mode string. If
the terminal has no enter_italics_mode string, then nothing will
happen.

This makes setting multiple attributes a bit less efficient, but I
don't think it's likely to make much of a difference since using
multiple attributes at once is so uncommon.
