added an extra key column (alt now on keyboard by default), added cyrillic
keymap, added a toggle to enable/disable overlays, added quick toggle buttons
to toggle primary two layers. Added some configurability using command line
parameters and environment variables.

Usage
-----
- $ svkbd-en

This will open svkbd at the bottom of the screen, showing the default
English layout.
- $ svkbd-en -d
+ % svkbd-sxmo -d

+This tells svkbd-sxmo to announce itself being a dock window, which then
is managed differently between different window managers. If using dwm
and the dock patch, then this will make svkbd being managed by dwm and
some space of the screen being reserved for it.
- $ svkbd-en -g 400x200+1+1
+ % svkbd-sxmo -g 400x200+1+1
This will start svkbd-en with a size of 400x200 and at the upper left
window corner.
+You can enable layers on the fly through either the ``-l`` flag or through the
``SVKBD_LAYERS`` environment variable.
+They both take a comma separated list of layer names (as defined in your
``layout.*.h``). Use the ``âº`` button in the
+bottom-left to cycle through all the layers.
+
+The virtual keyboard comes with overlays that will show when certain keys are
hold pressed for a longer time. For
+example, a long press on the ``a`` key will enable an overview showing all
kinds of diacritic combinations for ``a``.
+
+Overlay functionality interferes with the ability to hold a key and have it
outputted repeatedly. You can disable
+overlay functionality with the ``-O`` flag or by setting the environment
variable ``SVKBD_ENABLEOVERLAYS=0``. There is
+also a key on the function layer of the keyboard itself to enable/disable this
behaviour on the fly. Its label shows
+``â
`` when the overlay functionality is enabled and ``â`` when not.
