Revert "Due to perfomance issues at openboard start, in a network-attached storage context, I had to find some (dirty) optimizations in order to counter-balance the huge response time of the directory scans performed when creating the documents tree (very huge in slowest machines (HDD, low CPU, with a thousand documents)). The simplest solution (I found) was to let the opening of metadatas fail, and to prevent any scanning. This implied to introduce the page-count as a metadata. As this issue is not encountered with a standard use of OpenBoard (with local documents), no update operation (of every document) should be necessary out of the described context"
