HOT version 2015-10-15, remove Fn::Select

Bump the HOT version for the Liberty release, currently planned
for 2015-10-15 [1]

This is the same as 2015-04-30 other than the removal of the
last remaining CFN compatible function, Fn::Select, which should
now be replaced by path based attributes/parameters, e.g:

{get_attr: [aResource, anAttribute, <list index>]}
{get_param: [aListParam, <list index>]}
