Partition wizard should use local storage to save form

[Nicklas Nordborg]

This wizard is often used real-time in the lab. This means that it takes some time to do all steps and fill in the information. Due to problems (eg. wifi connection failure, etc) it is not always possible to submit the information to the BASE server, and the wizard doesn't allow retrying. The typical workaround is to take a photo of the screen before sending in the form.

It would be nice if all form fields could be saved to a local storage (if the browser supports it, but FF9+ and IE9+ should). Then, if there is a problem, the local information could be used to "replay" the data entry. This would also protect against other failures, such as a blue-screen, etc.

The partition wizard now remember all values in step 3 (Enter weight information). It is saved in the web browser local storage if the browser supports it (FF9 and IE9 should work). If something goes wrong with the registration the user can simply restart the wizard and select the same specimen tubes in step 1 (they are marked with a *) and continue as if nothing has happened.

Note that this feature is browser-specific and locally stored data can only be accesed with the same browser that saved it in the first place.

NOTE! Make sure to not use "Private browsing" mode of the browser since it is not sure that the data will survive, for example, a crash.
