Allow using extended regular expressions in the find dialogs

mgrojo · mgrojo · commit 48a8481b8563 · 2019-07-26T19:47:02.000+02:00
This adds support for searching "this|that" to find either "this" or "that" or using quantifiers like "{number}". The change applies to the Find/Replace dialog and the search bar. See https://en.cppreference.com/w/cpp/regex/ecmascript for details of the syntax. This raises the requirement for an external version of QScintilla to v2.11. See issue #1625
