Sync with dropbox

Hi,

Started playing with github a bit, so i decided to upload the modifications i made to floatnotes in case you would like to integrate them in your next version.

The changes allow you to specify a path for the sqlite database in the settings tab. Like this you can synchronize notes across browsers via dropbox for example.

However i know next to nothing about FF extensions, so you should check out my changes (not a lot actually: see commit notes) before using them :)


Thanks for great plugin
