[hibernate-dev] HSEARCH and fix version as topic

Sanne has moved the spatial queries issues out of 4.1 (rightly so) but entirely cleared the version number even for issues already fixed. I have created a temporary version `spatial` to carry issue fixed in the geo branch. We will merge this version with 4.2 or later if it really takes more time. What do you think of these topic versions for big features / issues that are made of multiple issues and live in a topic branch for a while? Emmanuel
