[IAEP] Lion Activity

[Tony Anderson]

The Lion activity (https://wiki.sugarlabs.org/go/Lion_Activity) has been 
added to ASLO (activities.sugarlabs.org).

It is suitable for testing by localizers. The current version allows a 
user to select a language (from those on the XO) and
an activity (from those installed on the XO with po directories). The 
user then sees each string in sequence. Once the user
is satisfied with the localized string, a click on 'accept' moves to the 
next one. When finished, the screen shows 'done'.

The activity writes a xx.po file to the selected activity for the 
selected language xx. It also saves the original as xx.po.orig for
checking.

To be useful, the po file must be compiled into an mo file - not yet 
implemented.
