Errors test-suite overhaul

Use makefiles instead of a make.sh script
Expected results are in individual .stderr files instead of the expected.log file
Add errors test-suite to Travis testing and 'make check'

+# Makefile for errors test-suite
+#
+# This test-suite is for checking SWIG errors and warnings and uses
+# Python as the target language.
+#
+# It compares the stderr output from SWIG to the contents of the .stderr
+# file for each test case. The test cases are different to those used by
+# the language module test-suites. The .i files in this directory are
+# used instead of those in the parent directory.
+#
+# When adding a new test case, be sure to commit the expected output
+# file (.stderr) in addition to the test case itself.
