Various fixes for pattern editor 

- Fix for vertical scroll bar being too far to the left.
- Fix constructor not initializing from const char pointer properly
- maxcolumn not being set for console text lines causing crashes on empty pattern  evaluation
- A replacement using replace all is now undone in one step.
- Find/replace no longer need to have enter or return key to accept text. You can use arrows or shortcuts.
- More efficient search replace implementation with plans to add even faster.
- Tooltips added to find/replace window
- Providers now save both horizontal and vertical scroll positions when switching to another one and restore them when switching back. This is independent to the cursor position which is also saved.
- Pattern editor no longer takes focus when changing providers via a tab click. This has the effect that menus won't change by just clicking on a tab.
- Small fixes and code refactoring.
