Update showcase slider items
Edit nivo slider's starting positions
Modify jQuery filemanager

Provides users access to unique userfolders stored on the server to provide
some personal file storage e.g. for posting photos. This access will be
restricted only for own user accounts and without sharing the direct link URL
nobody else see the other's files except for admins (they have access to the
root directory and therefore to the userfiles directory, too).
Temporarily add new images to the blog module

For now new images were added to reflect the recent news. Later there will
certainly be a specific section in the Admin Panel for the blog slider where
those images can be stored in the "uploads" directory and therefore won't show
up in the repository anymore. Before the implementation completes, we include
every new slider item separately to the repository.
Update .gitignore
