Update DataSaverPlugin to use browser localStorage when possible.
|Reported by:||Tiago Teresa Teodósio||Owned by:|
As there is a 4KB limit on the cookie size, larger form data can't be saved. I propose the usage of browser localStorage when possible.
There is a proposed implementation attached, based on datasaverplugin/trunk/datasaver/htdocs/datasaver.js?rev=8703
