*	Reindex tickets on server start if no index exists	Florian Zschocke	2017-03-05	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	Check if tickets need to be reindexed when the server starts. This is the case if no ticket index exists. In that case the ticket index is built. This is done during the start of the `ITicketService`. For this the interface of `ITicketService` needed to change. The `start` method was defined abstract and the specific ticket services had to implement it. None does any real starting stuff in it. The `start` method is now final. It calls a new abstract method `onStart` which the specific ticket services need to implement. In the existing implementations I just changed `start` to `onStart`.
*	Introduce an index version for the ticket index	Florian Zschocke	2017-03-05	1	-0/+98
	In order to be able to update the index definition, the ticket index is assigned a version number, 2. This way the definiton can be updated and compatability with existing index files can be checked. The actual index is stored in a directory of name `indexVersion_codecVersion`. This wayit is veriy easy to check if an index of a certain version exists on the filesystem. It allows to have multiple indexes of different versions present, so that a downgrade of the software is possible without having to reindex again. Of coure, this is only possible if no new tickets were created since these would be missing in the old index. A new class `LuceneIndexStore` is introduced, which abstracts away the versioned index directory. The idea is, that this provides one place to keep the Lucene codec version and to allow to code compatibility rules into this class, so that older indices can still be used if they are compatible.
