[Toaster] [PATCH] toaster: Disable add layer button when input is empty

[Belen Barros Pena]

From: Belen Barros Pena <belen.barros.pena at intel.com>

The 'add layer' button in the project configuration page
is enabled when you select a layer from the type ahead.
However, if you delete the layer name, the 'add layer'
button remains enabled, and if you click it, the last
selected layer from the type ahead will be added to the
project.

It is probably better to disable the 'add layer' button
when the input field is empty.
