This MR brings in a GitLab-CI pipeline.

The pipeline consolidates a docker builder, then sequentially builds kstars and runs all tests, including UI tests.
Because the size of the build folder is large, the pipeline uses a single stage to run both build and test.
docker/Dockerfile provides a builder image, currently stored as tallfurryman/kstars-ci.

How to record the activity of the test through xvfb-run:

xvfb-run --listen-tcp --server-num 42 -s "-ac -screen 0 1920x1080x24" \
    bash -c 'sleep 1 ; QT_QPA_PLATFORM=eglfs make test ARGS="-VV" ; sleep 15' & \
ffmpeg -f x11grab -video_size 1920x1080 -i :42 -codec:v libx264 -qp 0 -preset ultrafast ~/test_record.mp4

This is a single-line command producing two bash jobs. The tests run in the background, and the recorder on foreground.
Press 'q' to terminate ffmpeg properly during the 15 seconds given at the end of the test. Video is recorded to ~/test_record.mp4.v

Add facility in Align module to set a custom target module. It used to be always based on current mount target, but under few circumstances, the current mount coordinates could have deviated from the desired center target due to a variety of reasons. Now the align module has access to the target we are interested in centring, regardless of current mount position

Checking dithering before focus check to avoid overlapping of both actions during pre-capture checks

5 seconds may be too short in slow architectures.

Add pre-release warning to About page so that users can differentiate between beta and stable builds

Add concept of Proxy Devices which are devices that implmenet a different interface of a concrete device decorator.

All INDI devices are initially created as Generic Devices and then decorated to add additional functionality (e.g. Telescope). The telescope driver can also offer additional functionalities that are usually implmeneted in a different interface (e.g. Focuser or Weather). In this implementation, we create a proxy device if we detect that the parent device is not a generic device, but already one that was assigned a specific interface. The difference is that a proxy device does not delete the parent decorator.

Summary: when the focuser temperature is not available, the autofocus on
temperature change should make use of the observatory temperature as a fallback
(as stated in the v3.4.3 release notes). This is currently not the case.
This commit refactors the focuser and observatory temperatures to make both of
them available to the autofocus trigger feature.

Test plan:
- Connect the observatory simulator
- We need to connect a focuser simulator without temperature handling. To do so,
  I had to comment the temperature in the INDI simulator and recompile it.
- Perform autofocus
- Create and start a sequence
- Change the temperature in the observatory simulator and click the refresh button
- Verify the autofocus is triggered

FIXED-IN:3.5.0

skip non-guide blobs in guider::newFITS, improve reaction to lost stars in dither, remove getLastStarPosition.

Use the stream-like syntax of qDebug instead.

Fixes commit 82569890.
