Auto-Ranging Time Formatting For Menus (hh:mm:ss:mss)

Unifies time formatting in settings_list.c allows time format to
display as HH:MM:SS.MSS or any consecutive combination thereof
(hh:mm:ss, mm:ss, mm:ss.mss, ss.mss, hh, mm, ss ,mss)
works in INT and TABLE settings with the addition of flag 'F_TIME_SETTING'

Time is auto-ranged dependent on value

Adds talk_time_intervals to allow time values to be spoken similar to
display format:  x Hours, x Minutes, x Seconds, x Milliseconds

Table lookups merged or removed from recording, clip meter and lcd timeout
-String_Choice replaced with TABLE_SETTING or INT_SETTING for these
functions as well, cleaned-up cfg_vals that get saved to cfgfile

RTL Languages ARE supported

Negative values ARE supported

Backlight on/off are now Always and Never to share formatter with LCD
Timeout

Added flag to allow ranged units to be locked to a minimum index

merged talk_time_unit() and talk_time_intervals()

optimized time_split()

optimized format_time_auto()
