All UI Widgets emit "OnClose" event when being destroyed.
Minor fixes in UIDropDownList and UIImage.

String class now uses char32_t as base type, to be compatible with std::u32string.
Some minor refactor: replaced Uint32 type in hashes in favor of String::HashType. Replaced Uint32 type in keycodes in favor of Keycode.
Changed String::hash(String) from CRC32 to std::hash<std::u32string> (many times faster).
And more random refactors and small features in the code editor.
Fixed UISceneNode size, now it's set in pixels instead of dp to allow to always be the same size as the window.

Fixed a double delete crash when using UIDropDownList and UIWinMenu.
Now UI elements can be dragged even if the mouse cursor goes out of the window limits.
