Bugs in Multicharts Indicator SQ_KeltnerChannel

During replication of one strategy that uses SQ_KeltnerChannel indicator, I have found several bugs in this indicator.

First bug is that TypicalPrice is used statically in this indicator.
Based on online docs Close should be used here.
This variable can be used dynamically: Close, Open, Low, TypicalPrice, etc...

Second bug is that Average (SMA) is used here?
Based on online docs EMA should be used here.
This variable can be used dynamically: SMA, EMA, WMA, etc...

Third bug is that in the offset Range is used instead of TrueRange.

Not sure about this.

After all fixes I think KeltnerChannelDown, KeltnerChannelMiddle and KeltnerChannelUp should be unified too.

Not sure about this. Might be actually not a bug.
