2019-05-28	Fix java checkstyle handler.	Horacio Sanson
	The checkstyle handler is capable of parsing the new and old output formats. Unfortunately there are some particular output messages that matched both the new and old regular expressions: [WARN] whatever:11:7: WhitespaceAround: ''if'' is not followed by whitespace. [WhitespaceAround] This caused ALE to report extra errors since the message was being matched twice, once as a warning and another (incorrect) old formatted error. This MR fixes this by stopping any parsing using the old format regexp is any errors of the new format are correcly parsed. There is no reason to expect checkstyle to output both styles in the same report.
2018-11-07	Support older checkstyle versions	Johannes Wienke
	The output format used by older checkstyle versions differs from the one of new versions. This commit adds a second parsing iteration on the output lines with a suitable pattern to support both versions in parallel. Due to the differences in the order of matching groups this is hard to achieve in a single pass through the output lines. An appropriate test case is added.
