0.4.6 - Bug fixes and cursor improvement

Quite an exciting release that has Ox feeling more polished.

Added ➕

• Spaces can now be treated as tabs for indentation when moving or deleting, so if you are someone who uses spaces for indentation, your experience should be way better in Ox
• The X position of the cursor will stay in the same position when moving it up or down

Fixed 🔧

• Search can now find all matches and the issues of it not expanding its search past the buffer have been fixed
• Syntax highlighting now updates when undo or redo is used
