Unify behavior of About / Info / EMail-support

Closing as potential idea - lack of community interest

I just saw that in webui->iDempiere image button->Erros you can change the logging level and see log files. I think this should be removed or located in the preferences

I would suggest the following:
*Swing
**Preference (is not accessible for roles with Preference=None)
***Preference Tab
***Theme Tab
**Help
***Send Mail
***About
****Info Tab
****Context Tab
****Errors Tab

*ZK
**iDempiere image button
***About
***Credits
***Info
***Context
***Errors
**Preference link (only visible if role is allowed to change preference)

I think info/context/errors are not things the user change so it should not be located in the preference window. Moreover they are usefull information for administrators and should be available for every user so they can send it to the admin or read it while calling one. Since the support mail contains all this information anyway, i don't see the necessity for hiding it with role settings.

Furthermore I think, it might be a good idea to encapsulate the send mail function (probably in Adempiere.java, Env.java or in ADialog where there is already a similar function yet)for sending info/context/system/modelvalidator information. I also would like to create temporary files and attach them to the mail instead of sending plain text. This way you could use the same function for sending support mails from everywhere in the application and the admin don't have to look through a lot of plain text.
