Subject: [PATCH] webstaff: teach egGrid how to disable multiselect

For grids where it makes sense to allow only one row to be
selected at a time, egGrid now supports a "-multiselect"
feature that:

  * disables generation of the checkbox column
  * disables control-/shift/command-click to multiselect
