Fix to allow scanning of Spring-Boot jars or WARs, when the scanner is not running within that jar or WAR. (#209) Thanks to Yunior Betancourt for the bug report.
Also adds the ability to find and scan library jars within jars, contained in the lib, BOOT-INF/lib, WEB-INF/lib, or WEB-INF/lib-provided directories of jarfiles, even when these directories were not listed on the classpath using a URL like file:/path/to/my-spring-project.jar!/BOOT-INF/lib/libjar.jar. By automatically adding jars in these lib dirs to the classpath for scanning, this simulates the implicit adding of these directories to the classpath by the Spring-Boot classloaders, again for the case when you are scanning a Spring-Boot jar or WAR, but the scanner is not running from within it.
