In order to stay consistent with other layouts, the bottom line has been
re-arranged and keys dimensions have been optimized (based on the
`terminal` layout, which has similar features).
Furthermore, the ç/Ç keys in the 'normal' views have been replaced with
./, so that all diacritics are on the same view.
This commit also fixes the Backspace key behavior.
Due to an excessive amount of keys in the `eschars` view, one of the
rows would overflow the screen. This commit removes the `Ç` key, which
is already present in the `upper` view.
A number of keys would not give the expected result, due to the lack of
a `text` of `action` property. Additionally, the layout wouldn't load
because of an old file format (it seems `bounds` are not supported
anymore).
This patch makes sure this layout can be loaded and used by squeekboard
v0.1.9.
