Display rule template after submitting

[cdupont]

After new rule template has been submitted, there are several possibilities:

• the rule compiles,
• the rule doesn't compiles.

If the rule compiled, we need to come back to the newly created rule template, without edit.
If the rule didn't compile, we need to come back to the edit pane with the appropriate error message.

The error message on the last rule submitted is included in the player's profile.

To display the infos in the edit pane of a rule:
   If player's profile contain last rule && rule name == rule template's name
      -> take the infos from the player's last rule
   otherwise take the infos from the current rule

See #108. There should be a mechanism so we know the current name of the rule being edited. We should come back on:

• old rule name empty:
  • it compiles: point back to the new rule created.
  • it doesn't compiles: add an entry in the templates section and point to it, edit pane activated.
• the old rule name is not empty:
  • it compiles: point to the new rule.
  • it doesn't compiles: point to the old rule but with LastRule informations in the edit panel.

Wouldn't it be better to add an temporary entry in the template list for the currently edited rule?
We could display the LastRule structure as a separate rule dubbed "New Rule".
The profile rule would always link to this one. If no profile, default template is displayed.
