tikz: use tikzexport (ie, tikzexternalize, t2.7.5) (#1)

Temporary situation: the content of xmPreamble is to be moved into ximeraLatex (ie, ximera.cls...)

* test tikzexport

* test tikzexport

* only one xourse

* no .ximera-local

* no optimize (for tikzxeternalize)

* add veryclean

* update xmPreamble; uses adhoc  .ximera_local !!!

* config.txt: temp hack

* use .png;

* also compile calculus1

* only testxourse

* compile all

* xmPreamble: set isXourse; use mutool (and not dvisvgm); use t2.7.5

* cleanup

* use -full ...

* reset serve-ximera
