feh: Set the default theme explicitly to 'feh'

feh uses argv[0] to set the default theme, because
feh is wrapped this will be .feh-wrapper. This makes
it hard to use the configuration on multiple systems
and can be confusion. Therefore the theme is explicity
set to 'feh'.
Update feh from 2.11 to 2.12.

The relevant source code of giblib was imported into feh,
therefore giblib is no longer a dependency.

yi: improve expression

Disable Haddock docs so that it actually builds (bug in GHC 7.6.3), make
pango optional (OSX people often complain), tell the binary where to
find various libraries needed at runtime (currently it could not find
even its own library).
