This update makes better use of the Enum class capabilities
and reduces the code to something simpler and clearer.

Will be used by the ExperimentEditor tests

This allows for not calling the update process when --help is
passed and allow more fine grained control of which sub command
does it. For example, it doesn't make sense to create the cash
if the refresh_env sub-command is called.

In order to avoid having the reload again and again the docker
environment available, create a cache file if not existing on
startup.

This also add a command to manually refresh the cache if needed.

This widget will be used by various editors which have
lists of sub-editors.

The latest version of beat.core's dataformat schema has changed
the way basetype is defined. The code now supports both version.

Note that this simple parsing can be done due to the fact that
all the inforations are stored in the same schema file.

For example, if a default Algorithm can't be constructed because the
prefix used lacks the reference datformats, show the exception message
rather than make the application crash.

Same for property related methods.

Space before : when there's a formula

That can be one or more of:
- New
- New version
- Fork

It depends on the asset type.

Until now, only the prefix path was passed around. However.
there are cases where more information is needed like for
example the current user when creating new assets.

This commit also fixes the parameter handling of the editor
command which was duplicating what was already done by
beat.cmdline.

Depending on the asset type, it can be:
- A new asset from scratch
- A new version of an asset
- A fork from an asset

**WARNING** not all asset types can be forked.
This will fail accordingly.

**WARNING** not all asset types have version support.
This will fail accordingly.

**WARNING** not all asset types can be created from scratch.
This will fail accordingly.

This is because the support for ProtocolTemplate comes with this
version as well as better support for creating new assets.

This wasn't following the asset name properly

The prefix path is going to be used by all editors.[widgets] Remove field and test_editors

These were serving demonstration purposes. They are not needed
anymore.
