[Localization] Lion activity version 2

[Tony Anderson]

Hi, Chris

i was able to complete the functionality of the Lion.activity (version 2 
in ASLO). However, since I am not capable of providing translations for 
any language but English, testing has been limited. I was able to 
'translate' the Chat activity to Urdu (using English text for the 
translated messages). The pocompile tool is included in the bundle so, 
there should be no need for other tools.

The translated po file was compiled to an mo file. When I set urdu as 
the language in Sugar 0.106 on an XO-1.75, the Chat activity showed 
English text where Urdu would be expected. Note: in 0.106 there is no po 
file for Urdu, so the Lion activity presented the strings from the pot 
file. (copying it as ur.po). The activity saves the original po file as 
ur.po.orig (or xx.po.orig where xx is the language). The original mo 
file is overwritten.

I believe with this activity, the Nigerian project could translate the 
eight activities to Yoruba in a matter of hours (or let me know what the 
problems are).

However, the important goal is that it is simple enough that our users 
in schools can themselves translate activities to their own native language.
