Bugfix in hex_container.
Improved mk_project.sh.

It now tries '.' when PARSIFAL_DIR is not set.
It also allows for complete path as argument.
New PContainer: conditionnal_container(condition).

Fixed typos on other containers.
New PContainer: trivial_union.

It is now possible to have a Parsed/Unparsed alternative.

The idea was to allow for quick parsing of SSL/TLS messages by not enriching certificates.

New type_handler in parsifal_tool: ASN.1.

The handler should be improved to produce a clearer value.
