if a ticks_count is defined (!= 0), round the value to them ('ticks')
and draw finally some gaps.
Also an important issue: since the bar needs to be 'homogenous', they may won't
match a given height. Some value tweaking will be necessary then.
An alternative would be a not homogenous bar, what is worse I think.
The values, when there are 'ticks', get rounded up somebit. So they get turned on,
when half of them is reached - or so.
new options (see awesomerc.5.txt for a more detailed description):
border_width
border_padding
fg_off
ticks_count
ticks_gap
