Core: don't load bloom filters by default

This change just changes the default for index.codec.bloom.load to
false: with recent performance improvements to ID lookup, such as
#6298, bloom filters don't give much of a performance gain anymore,
and they can consume non-trivial RAM when there are many tiny
documents.

For now, we still index the bloom filters, so if a given app wants
them back, it can just update the index.codec.bloom.load to true.

Reflect that 'field_value_factor' is only in 1.2.x

While the blogpost http://www.elasticsearch.org/blog/2014-04-02-this-week-in-elasticsearch/ states, that feature #5519 was
added to 1.x, the release notes for, e.g. v1.1.2, however tell otherwise.
Only the release notes for 1.2.0 list #5519 as a new feature.

Since the 1.x docs deprecate/discourage from using `_boost`, and seemingly give a migration example at
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/mapping-boost-field.html#function-score-instead-of-boost
users of 1.1.x should be warned.
