[TYPO3-core] RFC: uninitialized variables code cleanup

[René Fritz]

I just did some commits in t3lib/.

I made the changes like we discussed.

Additionally I fixed some small bugs like wrong variables used because of 
wrong names. Etc.
2 times $TYPO3_CONF_VARS was used without 
"global $TYPO3_CONF_VARS;" which means now it will do something ...

t3lib_tsfebeuserauth::extIsEditAction() did not do usefull before. I hope now 
as the code is activated it do what it should.

I also found other simply not working code because of missing variables. I 
marked those positions with FIXME.

Some more todo in t3lib but that needs a bit more time.

René
