Nils Wallménius b311367481 *** Lang v2 cleanup (FS#6574) *** 
1) Introduces apps/features.txt that controls which strings are included 
for each target based on defines.
2) .lng and .voice files are now target specific and the format versions 
of both these file types have been bumped, which means that new voice 
files are needed. 
3) Use the 'features' mechanism to exclude strings for targets that 
didn't use them.
4) Delete unused and deprecated and duplicated strings, sort strings in 
english.lang

Some string IDs were changed so translations will be slightly worse than 
before.
