Revert "Comment out syntax checking in mediawords_reformat_code.pl"

This reverts commit 9e152e8245d94194bd20506c3ee658f1c30bf6c3.
Make MediaWords::CommonLibs pass the compile test
Add comment explaining why the syntax check is needed
Install a newer Gearman (v1.0.6) from a PPA repository instead of using an Ubuntu-provided Gearman (0.27 in Ubuntu 12.04) which is too old and buggy
In the gearmand wrapper script, test if Gearman is up-to-date
Fix typo (and also make "update_gearman" branch recompile dependencies on Travis)
Merge branch 'update_gearman'
Merge branch 'test_syntax_before_reformatting'
add support for num_words, sample_size, include_stopwords, and include_stats params for /api/v2/wc/list'; Moose-ify MediaWords::Solr::WordCounts
Merge branch 'master' into RELEASE_20140325
