Subject: Keep a local picsorter_deleted too.
X-Git-Url: http://git.scottworley.com/picsort/commitdiff_plain/d1309d5a15f015c52ff48ea52b028f47ca7723e8?ds=inline;hp=d1309d5a15f015c52ff48ea52b028f47ca7723e8

Keep a local picsorter_deleted too.

Don't unpack it from localStorage every single time it is needed.
Read it in once and write it back when it changes.

Note: This would make updates from multiple tabs running picsorter
on the same domain clobber each other's updates.  So don't run
multiple picsorters.
