#531 Remember if a search string is a regex

[Victor Porton]

When selecting a previously entered search string in "Search and Replace" dialog with Alt+Up, it should be remembered and restored whether the search string is a regular expression and automatically set/reset "Regular expressions" checkbox.

One almost never does regex search with non-regex string or non-regex search with a regex string.

Probably also should be stored and restored "Ignore case", "Whole word". It is disputable.

[Skeeve]

Maybe also the replacement which was used? So "scrolling" through the previos search strings would also scroll throught the replacement strings at the same time.

[Roman Tsourick]

With such unconditional synchronization flexibility is reduced, switching back from replace string after its modification to search one is no longer possible. Isn't it?
