Closes #113 (closed) And also:
- offers a new design of the XML viewed in the browsers
- embed xsl for modern browser support (tested with latest chromium and firefox)
- log xml cleanup
- check that the asm arguments are both present before enabling the launch (and show in red what's missing)
- fix a crash due to double delete (QTreeWidgetItem should only be deleted from children to parent, if a parent QTreeWidgetItem is deleted before its children, it generates a segfault)
- new: 5 tests were added for the action state machine app (3 for command line test and 2 using the autonext feature using simple SCXML files and testing there is no crash)
