Adding spec for Rake silent behaviour.
Avoid Float's automatic exponent output for very small values.
Noting the MIT licence in the gemfile.

Load indices always in the same order
Merge pull request #599 from grin/master

Indices should always be loaded in the same order
Index order still matters.

Rookie mistake... shame I'm well past being a rookie.
Call realpath on pathnames for the generated configuration file.

Necessary for those who symlink log, tmp, etc in a rotating directory
deployment.

With:

eg, if I: ln -s /app/log /app/releases/3/log

Then with this change the log dir is /app/log, without it's
/app/releases/3/log.

They both end up in the same place on the filesystem, but "fun" occurs
when /app/releases/3 eventually gets cleaned up.
configuration.rb's calls to realpath expect directories to exist, which broke some tests.

Call realpath on pathnames for the generated configuration file.
Provide the :minimal_group_by? option to avoid extended GROUP BY in sql_query.

This is for MySQL, which often doesn't care about proper SQL statements. To use it, just add the following within your index definitions:

    set_property :minimal_group_by? => true
Keep delegations together, and just under the private marker.
Realtime sortable fields are now added as attributes too.

Realtime indices don't have the option of supporting properties that are both fields and string attributes, so we return to the old _sort workaround.

:order arguments aren't automatically translated though - I'm not sure we want to add the overhead of loading full index definitions just for that purpose.
Symbols are translated into column references for realtime indices (like SQL indices).
Realtime sortable fields with symbols instead of columns are handled appropriately.
Suspended deltas were updating core indices as well.

That's not cool. This closes #609.
Do not clobber :select option in facet search
TS now requires Sphinx 2.0.5 or better, so let's include the Riddle tweaks accordingly.

Closes #618.
