Fixed NPE in REST API if an invalid data format was used
Made SML registration IP and hostname configurable (see issue #49)
Existing service groups can now be subsequently registered to the SML (see issue #51)
The "SML registration" pages now contains a note, if the SMP is already registered to the SML.
The default page of the PEPPOL Directory was changed to https://directory.peppol.eu - because of the very special https setup currently used, an update to the PD client library v0.5.1 is highly recommended
An error prevented Business Cards from being imported correctly - Thanks Ger for pointing this out
An exception when using the PEPPOL REST API in combination with an Endpoint without an URI was fixed
The Docker image got vim by default (see issue #45)
