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
Don't reformat test data files because Perl::Tidy replaces some Windows newlines ("\r\n") with UNIX new lines ("\n") and so the crawler test fails
Fix typo (and also make "update_gearman" branch recompile dependencies on Travis)
Show build status only for the "master" branch [ci skip]
throttle to 100 connections a second to prevent running out of ports in TIME_WAIT
Merge branch 'master' of https://github.com/berkmancenter/mediacloud
Merge branch 'update_gearman'
Merge branch 'test_syntax_before_reformatting'
