New features and unit tests enhancements

[FJBDev]

• Adding the possibility to configure a User Agent for each custom map provider

• Added the possibility to export the current map view to an image file (jpg, png or bmp) (Per feature request)

• Unit tests: Fixed the persistence manager issue and now the FitLog and FitLogEx tests are operational and successful

Unit tests 100% successful

See, I added mnemonics 😃

The action name is a little bit long and contains words which are not needed in the short name, I would name this action e.g. Export Map As Image. When a longer description is needed then it could be displayed as tooltip text

An improvement could be to also export it to the clipboard.

I've not yet reviewed the code, in which format is the image saved? You should keep in mind that images can be displayed in the map, so jpg or png 24bit should be used.

Ok, I will shorten the text

The export dialog gives you the choice between JPG, BMP and PNG.

@wolfgang-ch I have updated my PR with your suggestion and I have added the action to export the map view in the clipboard

Can you put the export actions into a submenu action (similar like Dim Map),

E&xport Map
-- As &Image...
-- To &Clipboard

Done. I also updated the PR screenshot.

Something strange happened, before I merged this PR here with github, I resetted FJBDev branch in my repo to my main branch because I saw this commit as my last commit in this PR. Then I merged and squashed it here with github, but now I don't see any of your modifications in my FJBDev branch.

So I reseted FJBDev in my repo to your last merge 53b9fe7

Can you create a new PR ?

There are still some ??? how this github merge works

@wolfgang-ch
Weird.... Github can be a pain sometimes. I hope we can resolve those issues soon.

I have created a new PR with the same exact modifications here
