Changing non-standard Fortran syntax introduced by A. Filhol that is not accepted by GFortran. Correcting small things and updating the script for compilation of Esmeralda with GFortran. Esmeralda built with GFortran has been tested and everything seems to work correctly.

Fix minor incompatibilities of the code with gfortran
Only tested on MacOS X

Removing non-needed "implicit none"! To the users of the library: when a function or a subroutine is within a module, the global "implicit none" declared at the beginning of the module propagates to all procedures within its scope.
Redundant "return" statements before the end of a subroutine/function have been removed.
Change line terminators from Windows to Unix ...

Build set up ci

See merge request !1

Changing things related with esmeralda_version.template and commenting some lines calling non-existing procedures introduced by A. Filhol (to be checked and repaired lately). Changes in Normalize_laue to avoid NaN in error analysis when the pointer to particular reflections toward independent reflections is outside the limits.

2- Now manages the default working directory for macOS
   Subroutine CheckWorkingDirectory
   On macOS it should not be /Application or a directory inside the bundle
3- Save_Orient crashed when
   - a .cfl contains a wrong directory
   - when using a dummy image (12/02/2020)
4- function NullToSpace(astring)
   Useful for printing directory//char(0)//filename

Name of dialogue routine starts with DLOG_
Escape key: center window and resize it if necessary
Tab key: maximise window size

4 crashes solved mainly due to unprotected file I/O
About dialogue improved
etc.
There are still problems with multiple monitor configurations. A bug in Winteracter.

Crash on CALL WglSelect(1, 0, 2) in routine setup_OGL()
A "Use winteracter" is necessary since Winteracter v12

* "Output Reflection Files"/"List of Reflections in Detector"
In the case of a simulation only, "Reflections_file.hkl" file was empty.

* file Reflections_file.hkl
Added date & Time + CFL file name to avoid confusions

* CFL file with "IMAGE_FILES 0"
In that case "Generate a Dummy image" is compulsory to activate icon IDT_Calculated.
A click on the icon IDT_Calculated crashed Esmeralda.
In Subroutine save_orient() I added a test
    if (.not. dummy_image) call Output_Indexed_Reflections(LaueDiff,Cnd%dmmtol)
But why "Generate a Dummy image" ? See below.

* CFL file with "IMAGE_FILES 1"
This is Okay even if the file is not found.
In that latter (thus 0 image file) icon IDT_Calculate is active and works and their is no need of a "Generate a Dummy image".
This is weird as compared to the previous case. 

* For macOS only : double screen set up management
Thus MyWDialogShow() is used instead of WDialogShow()
The Alerts cannot be re-positionned !
Winteracter 13 should solve that

Windows : Lawson explained that this is already supported.
macOS : here my solution
Linux : a similar solution certainly exists

with macOS and Linux the dialogues open exactly in between of the 2 screens. Vey unconfortable indeed!
I added routine that get from macOS the screen number and size and then position dialogues and windows by acting on WDialogShow and WindowOpen. 
The exception is WMessageBox but Winteracter (Lawson) told me they will add an option making possible to the set positin of this type of alerts.
Warning: the code is not final. I will make it more compact soon.
