WS-84 MONO_DEBUG should be set in environ script

To work around issue in Mono 3.4, we need to enable
MONO_DEBUG=explicit-null-checks.  This should be set
in the environ file so that it will be set wherever
wesay apps need to run (e.g. installed, debugging
from monodevelop, etc).

Use LiftSynchronizerAdjunct for Send/Receive operations on LIFT

This class was created in Chorus some months ago to customize the S/R
for LIFT, in particular using the right branch for the current LIFT version,
but WeSay is now configured to use it.

WS-161 SE Asian scripts are not correct

Additional changes were required to deal with
cases where the language needed to be specified
to identify the font type that should be used
where the font supported multiple languages. In
particular, this made the khamti language show
the correct format instead of the Burmese format
supported by the Padauk font by default.

WS-161 SE Asian scripts are not correct

Realized that the variable I used may contain a
dash and additional characters following. Also
realized that the same code was duplicated in
four modules and was now big enough to make a
base method

Add dependency on gnome-control-center

In libpalaso/PalasoUIWindowsForms/WritingSystems/WSKeyboardControl.cs
If KeyboardController.CombinedKeyboardHandling is true, then it
shells out "gnome-control-center region layouts".

gnome-control-center is installed by default in Precise and Saucy,
but not in Trusty.
