Fix Sunspot Rails not using sunspot.yml log_level setting

Sunspot will now use the configuration class to obtain the log_level
setting. The configuration class will get the log_level from sunspot.yml
settings file. If it is not present, the configuration class will use
Rails' log level setting instead.

Fixed Rails server class spec of not associating the @config instance
with the @server instance.

Adds note to rake task informing user that it is destructive

The title of the task is a little misleading. The assumption could be
made that the task will just update the data via a reindex, when in fact
it drops the current indexes completely and starts over. This can be
very destuctive if you have a large data set which can takes weeks to
reconstruct.
