Various properties can be accessed directly via
TypoScript config settings.

* $TSFE->spamProtectEmailAddresses
* $TSFE->intTarget
* $TSFE->extTarget
* $TSFE->fileTarget
* $TSFE->baseUrl

They have been marked as deprecated.

In addition, some internal functionality is now
marked as @internal as well, somehow related to
the deprecated properties.
