New:  Support For Excluded Sites globally and per location setting

You can now set excluded sites that apply to all keyword settings &
user-specified searches by adding this to you INI:
[search]
excluded_jobsites[]="AcandiaAdvocate"
excluded_jobsites[]="AdWeek"

You can also specify excluded_sites for each location set like this:
; [search_location_setting_set.bellevue]
; name="Bellevue"
; location-city="Bellevue"
; excluded_jobsites[]="Craigslist"

If you have both global and keyword-level or location-set-level
excluded sites, the two lists are merged into one unified one when
processing the keyword set or location set.
