- Codechange: Introduction of Textbuf struct which not only holds physical data as length but also pixel-constrains (width) and information about the caret - Codechange: Move Clipboard function to OS specific file. Currently only Windows has clipboard actions - Feature: Editboxes, console and exit screen also accept the numeric-enter as a yes - Feature: Navigation through text with cursor keys is possible, as well as arbitrary insertion (also paste) and deletion; both backspace and del keys. Functions DeleteTextBufferChar, InsertTextBufferChar and InsertTextBufferClipboard handle input and deletion. Navigation is done through MoveTextBufferPos. - Fix: OTTD crash when opening 'add server' editbox - CodeChange: fix up some stringwidth calculations in gfx.c. You can get the width in pixels of a character by calling GetCharacterWidth().
