Feature/typo3 compatibility

Merge branch 'feature/typo3-compatibility' of https://github.com/TYPO3-typo3org/t3o_membership into feature/typo3-compatibility

The memberships can now get the option “no_filter” option. If this
option is enabled, the membershiptype is not visible as a filter. This
will be used for honorary members

Due to not being able to satisfy the "compare database"
in Install Tool, the option fulltext will be removed.

The hook is called, after a member record was updated.

The hook is used by the typo3_agencies Extension to
synchronize agency data.

The end_data field is required and needs to be set independently
from the cancelled field. The endtime field is still only set
if the cancelled date is set.

We set an endtime if the member has cancelled his subscription.
The endtime is set to the value of the "Beginn" field which
contains the end date of the current subscription period.

The unique subscription_no property is used to detect existing
member records. If a member record exists, it is updated, instead
of truncating the members table and inserting all records as new.
