Let the admin overwrite the content of the
"Terms of Service" page by copying the original ToS
template and creating a local file (same procedure as
for the configuration). This file is not versionized.
Note: This is a breaking change, since the existing
tos textfile is moved. This should be mentioned
in the update comments.
* ToS text file changed → move file from "/tos_text.php"
to "/lib/tos.local.txt" and remove all HTML und PHP Tags,
leaving a regular text file.

Move the include of the original and the local
configuration file into the settings file to reduce one
includes in each file, have all settings in one place
and remove unneccessary code from the config file
(which makes it easier to copy and change it).
