Refactor fluid to Fusion templating

[Sebobo]

This can be similarly done like in the history controller of Neos and would lead to the following benefits:

• Easier to modify and extend
• We don't use form helpers for now but later replace the used form html tags with fusion forms in Neos 5.0 (planned)
• We want to have Fusion based backend modules in the long term

@sbruggmann @mficzel should we do this together with #6 or do it non-breaking and just with small improvements?

[Sebobo]

Should we also think about showing the hit counter and creation date?

[mficzel]

(yes) If hit counting is enabled.

BTW: I consider enabling hitCounting by default a problem but this is in the redirecthandler package itself.

[Sebobo]

Yes me too, see #11
