Created layout preset library (#375)

[Atria1234]

First step:

• Add translations
• Find final place for the dialog button in the menu
• Find good way to show layout preset images
• Make Layout folder location configurable

Next step:

• Implement synchronization of layout presets from somewhere (github repo probably)

To test:

• There should be "Layouts" folder in folder with AnnoDesigner.exe
• Create arbitrary folder structure in that folder, if you want
• Put zip files into any subfolder in "Layouts" folder. Content of that zip file:
  • layout.ad (has to be named like that)
  • info.json (has to be named like that), for structure, check JSON schema in Layouts/LayoutInfoSchema.json file
  • any *.png, *.jpg or *.jpeg image files which should be attached to that layout

Same info is also available in Layouts/Readme.md

There should be "Layouts" folder in folder with AnnoDesigner.exe

Is this only for the purpose of the fix and will this default?
If is, then i want to request that this folder can be changed as default to other drives/locations
settings wise

You mean that root layout preset folder should be configurable somewhere by the user?

In anyway the Layouts Directory, rest ofc is default Program directory

I have as example my Exe on C, but my layouts on D
(if windows crashing, i do not lose my Layouts, and the Program is easy to download :D)

I'm aware there is a lot of conflicts, I'll fix those if you think this is good way of going forward with this
