Introduced PreprocessorData

This commit introduces a better way to help
preprocessor to centralize data. It then allows
different types of queries, that are simply processed
during the preprocessing phase.
Added UI to post status

This commit provides a small fix for the banner, as well as
an UI for posting status updates.
Initial work

This commit provides a better object writer script
as well as some cleanups in order to prepare the
work to come.
Added missing files
Converted objects API and reliable generator

This commit provides a new API for Facebook objects
as well as a reliable generator. From now, many
processors should not be needed, so the processing
task is now greately simplified.

Loaders are still needed since they are the bridge
between C++ and QML and properties cannot be exposed
dynamically in QML (they need to be described with
Q_PROPERTY).
Added object list loaders

This commit provides the object list loader, based on the
principle of object loaders.
Added the capability to get posts

This commit added the capability to get post back.
Restore parity with master

This commit restores parity with master, making qfb-mobile working
again. However, the post operations are not yet ported to a simplier
API.
