SOLR-3211:  allow parameter overrides when testing spellcheck collations

  == spellcheck.maxCollationEvaluations ==
  The maximum number of word correction combinations to rank and evaluate prior to deciding
which collation candidates to test against the index.  This is a performance safety-net in
cases a user enters a query with many misspelled words.  The default is 10,000 combinations
which should work well in most situations. <!> [[Solr4.0]] [[Solr3.3]]
+ == spellcheck.collateParam.XX ==
+ For use with "spellcheck.maxCollationTries".  Override the named parameter (substitute XX).
 For instance, if user's query uses dismax/edismax and a low "mm" value was specified (such
as 1),
+ it might be desired to requre 100% of the query terms to match when testing collations.
 In this case, specify "". <!> [[Solr4.0]]  See
  == spellcheck.collateExtendedResults ==
  If true, returns an expanded response format detailing collations found. default is false.
 Ignored if "spellcheck.collate" is false.  Following is an example of the extended output
for the misspelled query '''Title:(hopq AND faill)'''   <!> [[Solr4.0]] [[Solr3.1]]
