Add support for Java stack traces (#1520)
There are 3 main types of elements which are highlighted: 1. The summary. This is the head of the stack trace and includes the name of the exception and a message. `Exception in thread "main" java.lang.RuntimeException: A test exception` 2. Stack frames. These make up the actual stack trace and include the full name of the method and the source. `at com.stackify.stacktrace.StackTraceExample.methodB(StackTraceExample.java:13)` 3. Omitted frames. This is a simple message that some frames were omitted. `... 27 more` Everything besides these 3 element types will not be highlighted.
