[Owncloud] database abstraction

[dev at c33s.net]

hi,

http://owncloud.shapado.com/ doesn't work for me, submitting a page
results in a white screen of death.
so here my feature request:

be flexible and add a database abstraction with propel
http://www.propelorm.org/ or doctrine http://www.doctrine-project.org/
this will make it possible to choose among many different databases. not
everyone wants mysql :)

greets
