[CDF-289] - Fixed windows .orient folder location
[CDF-289] - Updated commons-io lib
[CDF-289][REGRESSION] CDF is breaking at runtime in biserver 4.x due to unknown method call FilenameUtils.normalize( filename, unixSeparator )
	- upgrade of CDF's commons-io ivy dependency from 1.4 to 2.1 solves compile time errors, but in runtime the 4.8 platform still uses it's own ivy dependency of 1.4
	- https://commons.apache.org/proper/commons-io/javadocs/api-2.1/org/apache/commons/io/FilenameUtils.html#normalize(java.lang.String,%20boolean) is from commons-io 2.1 and above;
	- https://commons.apache.org/proper/commons-io/javadocs/api-1.4/org/apache/commons/io/FilenameUtils.html#normalize(java.lang.String) is the one to call for commons-io 1.4;
[CDE-311] MimeType resolver does not handle .svg files, thus sending an unknown Content-type in the response header
	- [cpf-pentaho5] new MimeTypeHandler calls platform's org.pentaho.platform.util.web.MimeHelper, defaulting to cpf-core's pt.webdetails.cpf.utils.MimeTypes (if first one is not able to resolve)
	- added unit tests
	- added missing log4j.xml to /test-src (fixes unit test logging)
[CDE-306]: Added default time out for interplugin httpsession to minimize the issue
[CDE-322] - Removed rule that required admin rights to access any file that is located at /system
[CDE-322] - Improved security check for access to files inside of system. Now only files that are within a Sparkl plugin directory are accessible without admin rights.
[CDE-322] - getSparklPluginIds now caches the results obtained on its first execution.
