Adding driver profiles feature to Ekos in order to support multiple local and remote observatory profiles

Disabled 30ms timer to update SkyMap since it degrades performance significantly and there is no reason for it to begin with

We now recompute precession corrections only if there has been a large
shift in time.

With dynamically loaded stars (DeepStarComponent), the star object is
recycled in memory to avoid the overhead of memory allocation and
construction. The new star data is re-initialized in a pre-existing
StarObject by calling StarObject::init() with the new data.

Since we added the lastPrecessJD much later, it has to be initialized
in StarObject::init(); otherwise, the catalog coordinates will not be
precessed when a previously existing StarObject is re-purposed for a
new star.

GUI:

Add updateCoordsNow() for situations when we need to force recomputation of coordinates regardless of time lapses. Use it where it is expected in the code.

Disable AlwaysRecomputeCoordinates by default. Set JIT update to be once per solar minute to enhance performance

In case of conflict in i18n, keep the version of the branch "ours"
To resolve a particular conflict, "git checkout --ours path/to/file.desktop"

...by adding the NO_POLICY_SCOPE flag as recommended by ECM's
documentation.
