Task/435 loglib the messages 2

### Description
Finished the transformation of the log message texts into a more ordered manner.
Also, removed all LM_RE and LM_RVE.

This issue resolves issue #443 
Also, after this, very little left on the log feature (issue #435)

Now, the discussion on these messages can start ...

Good point.
It's another thing still left for the next (and probably last) PR.
After finishing this PR let's talk and find all that is missing to terminate this.
For example, after a database error, when it starts working again, we would need a message telling about that.
Also these LM_I about 'successful' database operation.
And probably more stuff.
