Make meta data discovery compatible with fat jars

Most fat jar approaches, e.g. Maven assembly, have problems with resources at the same location in the classpath in multiple JARs. E.g. if two JARs being bundled into a fat jar have a types.txt file, only one survives.

One option to fix this would be to change the pattern that uimaFIT uses to search for these files, e.g. from classpath*:META-INF/org.apache.uima.fit/types.txt to classpath*:META-INF/org.apache.uima.fit/**/types.txt
