Add regexp fuzzy searching
Add regexp fuzzy searching

By setting the `advancedSearch` property to true the search entered will
be a fuzzy match and not a string match. This means that it will search
each character in order regardless of intervening characters. The basic
difference is this:

| advancedSearch  | search term | match           |
|-----------------|-------------|-----------------|
| false (defualt) | foobar      | bar(foobar)     |
| true            | rbr         | ba(r)foo(b)a(r) |
