[trunk] New /info command, reads text from info.txt.

Chapters are supported. Each line that starts with #name creates a chapter named name. Name does not support spaces and ignores case.

If info.txt contains chapters and no chapter is selected with /info command, then it will either print the file until the first chapter or if the first line is a chapter, it will return a list of all chapters.
