- Added 'Replace next' and 'Replace all' to Find command
- Fixed 'Previous' button that would search for the next occurrence instead of the previous one
- Improved UX
- Fixed find command window losing its owner whenever the Script Editor would be closed

- 'Find' window is now called 'Find/Replace'
- Improved the user experience of using the 'Find/Replace' command (mainly 'Next' button is looking like it's focused to indicate what the action will be when pressing Enter on a textfield)
- Fixed behaviour to work both on Windows and MacOS
- Fixed 'Replace all'
- Changed 'Replace next' by 'Replace/Find' for better UX

- Renamed "Find" to "Next" for consistency
- Replace all now replace all the text at once. Ctrl/CMD + Z now undoes all the replacements at once, instead of one by one
- Ignore case checkbox state is now saved when reopening the "Find/replace" window 
- Fixed minor bug where hitting Ctrl/CMD + F on a tab would throw an Exception

- Fixed 'undo' after 'Replace all' (it would undo one query at a time, now it undoes all at once)
- Added label next to "Next" button in case 'Previous' or 'Next' doesn't find any matching query.
- 'Replace all' does not match regex anymore (inputting '.' would have replaced all the characters in the text, now it only replaces all the occurrences of '.' in the text)
