New release around checksums

JDBMS_CHECKSUM : Added CRC32 computation on multiple input BLOBs (up to 10). So you are now able to compute CRC32 in single shot on multiple BLOBS (the CRC32 is sequentally updated with BLOB's bytes, null BLOBs are skipped during computation). I have implemented this feature because of a specific need in my job. I'll try to implement the same overload in JDBMS_JACKUSM package, it may be useful and more homegeneous.
Updated test_JDBMS_COMPRESS with the grant to be able to test the LZMA compression function
Updated JDBMS_JACKSUM with overloaded functions to make standard checkum computations simpler : now you can just provide the algorithm. The overload is available for BLOBs, filesystem file and text. The TEST_JDBMS_JACKSUM has been updated with code samples.
Updated JDBMS_JACKSUM with checksum computation on up to 10 BLOBS in a single time (like in JDBMS_CHECKSUM in this same release). Overload for light version also provided (you can only provide the algorithm for shorter PL/SQL calls). You can compare the JDBMS_CHECKSUM and JDBMS_JACKSUM for crc32 algorithm, althouh the JDBMS_JACKSUM is much more complete but a bit slower (around 2 times slower).
Completed the jmimemagic magic.xml file with chm mimetype. Hence, since now, JDBMS_JACKSUM will be able to detect chm files (from file or BLOB). Just reload the library to have this new mime type enabled, therefore just :
loadjava -u OJUTILS/OJUTILS -resolve lib/jmimemagic-0.1.0.jar
