Three of the current plug-ins generate deprecation errors when installed in 0.10

The Dropbox, SiteNotes and TagSuggest plug-ins all generate a "fatal" deprecation error when installed in Omeka 0.10. We would like to use a couple of these. Could someone advise on:
1) How to properly uninstall when you can not longer access Omeka's admin.
2) How to repair the deprecated code so each of these plug-ins will work within 0.10.
These plug-ins are currently going to cause significant problems for anyone who installs them.

The problem plug-ins are not actually "current".
