Recommend throw IOException or wrap IOExceptions with FacebookException

using facebook-java-api 2.1.1:

I'm attaching two possible patches. One patch wraps the IOException in a
FacebookException which is already being thrown by callMethod().  The other 
patch
throws IOException.  That is a more invasive change b/c it forces every API 
method to
throw it, but it is probably the preferred way the API should work.

As a bit of background, without any fixes to this, we will have to wrap all
ExtensibleClient calls in try {} catch (RuntimeException re){}, which is highly
undesirable.

sorry to have this fallen in the cracks, but I'm really torn.  I have been 
slowly
become a fan of the "fewer checked exceptions" (mostly coming from spring and 
what
not).  I believe most users will simply wrap with a try/catch and swallow 
errors, or
simply re-throw them to someone else higher above.. so as a RuntimeException it 
would
be better.. but like I said, we can discuss.
