Add the "webdriver-manager update ...." command.

webdriver-manager:12.0.6 is now in the dependencies.

The base image is now node:8 (and no more node:8-alpine).
Changed the way Java 8 is installed.
Install other packages (chromium, xvfb, libgconf-2-4).

The tmp directory is now directly created in the webdriver-start script.

Node version has been changed to 8-alpine because Java 8 was not available in node:7.10

Issue 23

Closes #23 and #24

See merge request !22

Robot will now stop recording and close websocket when a participant leaves the
room.

robot now checks for participants that have already joined the room and record
them on start.

There was a (non-problematic) typo in `should start transcribing stream on user
connection after start` test in `robot.test`.

Fixed it.

implement reco behavior

Closes #15

See merge request !21

robot now displays reco. as chat messages

The client controller now exposes a function to send a chat message via hublin.

Add base64-encoded avatar of hublot

client: define and implement libReco

Closes #3 and #13

See merge request !20

Extract keywords and propose recommendation links based on transcription segments which are sent by the participants

Allow chromium to access insecure content. This is required for now as not all
external services expose secured endpoints.

This should not cause a problem in practice, but is still bad. We should ensure
that this will not be needed in the future.

See issue #22.

fix external lib loading issue

Closes #21

See merge request !18

The external libs would not get loaded before running the behavior functions
that required them.

Move loading function call and add timeout to force them to get loaded before
robot start.

client: add libArchive feature

Closes #4 and #14

See merge request !17

robot now initialize lib.archive on start

Add client lib to archive transcripts of meetings.

Fixes some issues with project setup

Closes #19 and #20

See merge request !15

`yarn.lock` resolved packages with linagora GSO internal proxy registry. This is
not good if someone from outside GSO want to build the project.
Removing it.

`test` stage is defined by default. No need to specify.
(also job `test` is not the same than stage `test`)

Add `docker` tag to `.gitlab-ci.yml` to ensure CI is runned with docker-enabled
runners.

client: Add mechanism for loading external resources

Closes #11

See merge request !14

runner: replace parallel loading of resources with sequential one

Closes #17

See merge request !13

Add `client/external.js` which load third-party scripts passed into the
`externalLibs` array of the client config object.

The runner would load all the client resource files in parallel, causing errors
intermittently due to some resources depending on other ones.
This behavior was incorrect.

Runner to uses `resolveSequentially` that ensure that each resource is loaded in
order.

client: Add first version of robot behavior

Closes #11

See merge request !12

Implement first version of robot behavior. Currently, the robot listen for new
participants and, when a participant connect, start speech recognition.

The results of speech recognition are displayed in the console.

The robot requires the `start()` method to be called to begin. This method is
automatically called by the runner after loading all the modules.

Add speech-to-text function to hublot client side

Closes #6

See merge request !8

Replace description test with meaningful descriptions
