Added ability to parse data from Stoker.

Stoker (https://github.com/ibuildingsnl/OpenConext-stoker#output-format)
indexes edugain metadata and publishes this at a defined location.
The contents need to be parsed and displayed to the user to be able
to define which SP's are allowed to see which teams.
Upgraded jquery to 2.1.1.

Jquery dependant libraries are also upgraded: jquery-validation and jquery-ui.

Also added typeahead as dependency for autocompletion.
First version of registering allowed service providers to a specific Team.

By setting the property 'enableGroupzy' to true in coin-teams.properties
you enable this feature. This version uses an in memory store.
Refactored teams setup to use spring profiles.

Spring profiles is the default way to load different configuration
in different environments en contexts. The default profile for
teams is "openconext". One can enable the groupzy feature by
setting the system property *spring.profiles.active* to *groupzy*.
Fixed verbose logging when running tests and jetty.

Added specific logfile for c3p0 to play nicely with logback and upgraded
logback to prevent annoying unknownhostexception message. 
See for instance https://github.com/pedestal/pedestal/issues/201.
Only show the edit ServiceProviders button when groupzy is enabled.
Put flyway in a separate spring profile.

Since the teams application is not responsible for creating the
SQL schema we only want to create the hsqldb in local development.
Add how to run groupzy in README.
Added list of service providers on the invitation page.

When a admin invites a user to a team that user will now see
which service providers will have access to his data.
Also added a LetterOpener based on the ruby letter_opener gem that
will open HTML and TXT mails in a browser so you can see how the
email will look like.
Removed the profile groupzey-dev. This is now part of the dev profile.
Moved Stoker to its own library.

Depend on library.
Use jenv to manage multiple javas.
Depend on stoker 0.4

Remove unused MysqlTeamDao
Renamed findInvitations to findOpenInvitations
