Speeding up the loading of language lists
loading of language codes is now offered in a method in Aikuma.java, but it is yet to be called in main.java
Added a call to Aikuma.loadLanguages() in MainActivity
Updated lang code loading test
Managed to get Language strings to display on AddSpeakerActivity
Adjusted the speaker language list item layouts
Merge branch 'fastload' into addspeaker
Changed add speaker and settings layout to something acceptable
Changed FileIO.readDefaultLanguages to throw no IOException, instead return an empty list on a failed read
