[Go] 1 year limit on IEAs

[Mike Cherry]

UNIPROTs IEA are updated with each of their monthly releases.  So if  
you get their IEAs at least once a year you're fine.

The 1 year limit was set way back.  I think back in 2001 for the  
reasons Suzanna gave.  If the IEAs cannot be updated once a year how  
actuate are they?
