Pressing Tab was intented to insert two spaces, but for some reason it does not work anymore. This behavior is not useful so I removed the tab handler and now the cursor jumps to the next cell, which is the next word or the next cell after the text. See issue slisson/mps-richtext#42
MultilineSelection.ensureVisible() implemented (slisson/mps-richtext#31)
Merge branch 'master' into 31_EAP
