Elvis Stansvik 820a667190 Save case sensitivity and regular expression search options for the Contents 
and Reviews side panels to okularpartrc.

If these options are turned on they are now saved as:

ContentsSearchRegularExpression=true

and

[Reviews]
ReviewsSearchCaseSensitive=true
ReviewsSearchRegularExpression=true

respectively.
