[TYPO3-v4] install tool bashing

[Steffen Kamper]

Hi,

when we are on - the graphics configuration (IM/GM) is missing in 
introduction package as well.
I think the optimal situation would be that you don't need to go to 
install tool again to have a full working installation.

There are already search paths in install tool, so a function could 
check these for IM/GM automatic and offer for accept. If nothing is 
found it should be stay a warning that the graphic won't work as expected.

Introduction/password: we should do the same in 1-2-3. But don't name it 
  "password for your TYPO3 installation" - that's not correct. The 
password is for TYPO3 install tool only.
