Console: add support for displaying tab-stops

Without this it was necessary to convert pasted text into spaces
for them to display properly.

Since tabs are a valid part of a string, it's incorrect to assume
tabs can always be expanded to spaces.

Pasted text and console output now display tabs properly,
the tab still uses spaces for indenting though.
