Allow batch error handling

Sometimes poping up a new buffer is not really an option. eg. when
some script. So still allow for the old behaviour while the new
nice one is the default.

Fixes #48

+Errors are reported in a temporary buffer. This is to make error messages
+more readable. In particular when they contain stacktraces from the Java

+Note: the error might not be shown by vim. Check the output of |:message|
