accessibility: speakup: phonetic spelling while arrowing letter by letter

Browse source 
This patch includes an enhancement requested frequently on the mailing
list.[1][2] It adds a variable, cur_phonetic in the spk_vars, which can
be set as a module parameter, as well as in /sys/speakup/cur_phonetic.
This patch also documents cur_phonetic as a sysfs attribute in
sysfs-driver-speakup.

When cur_phonetic=1, it causes speakup to speak letters phonetically if
paused on the character while arrowing through a word.

When a user does not set cur_phonetic to any value, the default value
for it would be 0.

Description: This allows speakup to speak letters phoneticaly when arrowing through
a word letter by letter. This doesn't affect the spelling when typing
the characters. When cur_phonetic=1, speakup will speak characters
phoneticaly when arrowing over a letter. When cur_phonetic=0, speakup
will speak letters as normally.
