libnspr4 + libnss3 (+ gtkmozembed) transition

[Alexander Sack]

You might have noticed that we have a transition for libnspr4 and
libnss3 going on. Here some basic instructions:

For packages build-depending on libnss/libnspr, please change your
Build-Depends like

 libnspr-dev -> libnspr4-dev                                                                                        libnss-dev  -> libnss3-dev    

Please be sure that you remove any explicit depends on libnspr4 or
libnss3. The proper depends will now be detected and automatically
added to ${shlibs:Depends} by debhelper.

For packages using gtkmozembed you usually just need a respin against
latest firefox-dev.

If you need any support for this transition, please visit
#ubuntu-mozillateam on freenode.

Have fun,

 - Alexander
