Modular version by default, fixes multiple layouts bugs

[trilowy]

What changes:

• gitignore to have kanata exe directly into the project (particularly useful to dev)
• modular version by default (we might want to add a tag 1.0.0 on the previous version?)
• replaced 102d by <, easier to ready what this key does
• altgr layer upgraded with the latest 1dk layout version (^@ inversion)
• fix azerty symbols layer for ~ and `, they were dead keys
• let altgr on the numrow to allow azerty to do those symbols in dead key mod
• nav et symbols layers didn’t work very well with other layouts, as letters move and numbers are sometime on shift, etc, so I made an alias file by layout and all is variablised on the different mods (there is a PC/Mac version for each layout as shortcuts and some special characters might not be the same)
• I reverse back Enter and Esc to match the images but we can change it back easily if we prefer that way

Might fix #17

#13 done for Bépo

#11 also done but it might lack the proper documentation with images

This looks much saner, thanks a lot for your contribution!

I’ve left a couple nitpicks/suggestions, we can merge if you approve them.

I’m surprised I didn’t see that. Maybe it’s a recent feature ?
