[BUGFIX] Relation deletion rule does not support FOLDER to FOLDER

The importrule explicitly checked for FOLDER to DOCUMENT relations, but
there have been cases @ clients where they would like to remove FOLDER
to FOLDER relations, and more importantly: the description suggests it
can.

[TASK] Remove redundant mod4 declaration

Mod4 was never removed from ext_tables, and only TYPO3 6.2 shows this by
showing null labels in the moduleMenu in backend. Since mod4 never came
to fruition, this can safely be removed.

[TASK] Change referred v5 to v7 in text labels

When Decospublisher 4.0.0 was uploaded to TER, the official upload
mechanism reported errors. This resulted in multiple version bumps,
requiring me to bump the version to 6.0.0 to resolve any remaining
issues. Unfortunately, this also means the version reported in text
labels to lose support for deprecated tables needs to be raised from 5
to 7.

[TASK] Make update-script TYPO3 6.2-compatible

Update-script mechanism was changed between 6.1 and 6.2, to include
content within a standard template. Because decospublisher does the
same, this results in erroneous content.
