added noblogs/themes-misc as a dependency, and removed the corresponding theme patches.
This themes are not on wordpress.org anymore, so they will not be updated from upstream,
and thus we have to keep them in our own repo (but there is no need to separate patches
from upstream).

We might want to consider whether to keep them or remove them in the future.

Closes #6

Revert "contrariamente a quanto dicono nella documentazione, si può fare spacchettare tutto nella stessa directory, senza creare una directory wp/ per core"

Si può fare, ma se viene fatto un update di wordpress core poi si perdono tutti i temi/plugin/etc.

Ho cambiato leggermente la struttura delle directory generate, ed ho spiegato tutto dentro README.md

This reverts commit 19f27161.

contrariamente a quanto dicono nella documentazione, si può fare spacchettare tutto nella stessa directory, senza creare una directory wp/ per core

- moved themes related patches to patches/themes (yet to check)
- moved wp core patches to patches/core
- split the mega-patch for hyperdb in the individual edits. I removed the one related to nextgen-gallery since I think it is not relevant anymore (but I might be wrong)
