ASA and ASA_CAPI protocol IDLE property name is "Host"

[aehimself]

My custom property parser threw an error because it found a duplicate in property names. Turns out, the idle property was taking it's name from ConnProps_Host instead of ConnProps_Idle.

Commit was automatically included in the pull request open for MemTable's streaming support.

So please take commit #3 and #4 from it, not 3 only :)
