Merge pull request #56 from lategoodbye/master

Improve wildcard search, fix leaks and segfault
bug fix: don't assume that frame->next is zeroed before mbus_parse is called
only show timestamp in XML output if it is set (not all frames that goes into mbus_parse passes through timestamp), to avoid a lot of '<Timestamp>1970-01-01T00:00:00</Timestamp>'
fixed warning

updated XML files for test frames
remove the CUnit based unit test, since it does not work well (does not show which test that is failing...). instead we can use Stefan's nice generate-xml.sh which show exactly which test frames fails and the diff.
