- Added listByModulesAndStudent to CourseStudentDAO
- Changed BOM version reference to hardcoded version for compatibility
with different version numbering
Merge branch 'develop' into analyzer-plugin

Conflicts:
	pyramus/pom.xml
 - Added RepositoryId to PluginRepository (need to set these manually at
next db update & restart)
 - Merged Plugin management and loading system from muikku project
(support for snapshot versions)
- Removed setting of content type for plugin resources (caused unknown
mime types to be served stupidly)
 - Added DynamicAttributes to ix:extensionHook
