[FEATURE] Add absolute option to typolink VHs

In order to generate absolute URLs through the
Typolink ViewHelpers of TYPO3 Fluid, a new
fluid parameter "absolute" is added to the following
ViewHelpers.

* <f:link.typolink>
* <f:uri.typolink>

As typolink() is allowing this option, the generation
of absolute URLs behaves the same way as typolink()
itself does it.

Use it like this:

The ViewHelper code:
- <f:link.typolink parameter="23">Link To My Page</f:link.typolink>
generates:
- <a href="index.php?id=23">Link to My Page</a>

The ViewHelper code:
- <f:link.typolink parameter="23" absolute="true">Link To My Page</f:link.typolink>
generates:
- <a href="https://www.mydomain.com/index.php?id=23">Link to My Page</a>

The ViewHelper code:
- <f:uri.typolink parameter="23" />
generates:
- "index.php?id=23"

The ViewHelper code:
- <f:uri.typolink parameter="23" absolute="true" />
generates:
- "https://www.mydomain.com/index.php?id=23"
