In messages show the actual text user entered in Find and Replace dialogs
Previously we could put into a message a string where escape sequences
were already translated.
In the code, now we pass the original text together with the one
that is actually searched for. New `original_text' field was added to
GeanySearchData. A bug was fixed in document.c:show_replace_summary(): it
did not escape the "No matches found for ..." string.
Patch by Eugene Arshinov, thanks.
