Add tab completion to textinputs
This adds tab completion to textinput components. They can be configured with a completion function. This function is called when the user presses <tab>. The first completion is initially shown to the user inserted into the text. Repeated presses of <tab> or <backtab> cycle through the completions list. The completions list is invalidated when any other non-tab-like key is pressed. Also changed is some logic for current completion generation so that all available commands are returned when <tab> is pressed with no current text and similarly for arguments of commands.
