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.
