[BRLTTY] LibLouis support.

[Dave Mielke]

The latest development code now supports LibLouis. In order to include this 
support you'll need to ensure that LibLouis's development package is installed 
on your system.

The -c command line option, as well as the contraction-table brltty.conf 
directive, can be used to specify a LibLouis table. Simply prefix the LibLouis 
table's file name with louis:, for example: louis:en-us-g2.ctb

As always, please let us know what isn't working, as well as what can be done 
to improve this feature.
