Deletion: remove prematurely inserted internationalising code

Review by other developers has suggested leaving out code that could affect
the Lua API if fully utilised and which will be redundant until a
coordinated approach to internationalising Mudlet has been decided upon.

The remainder has been left in a form that WILL raise compilation errors
if the Qt I18n helper macro QT_NO_CAST_FROM_ASCII is defined to highlight
an area that will need further attention when translation to other
languages is attempted.
