[Titop54]

Changes on the readme.md, now with a bit more details, instead of 2 bare lines:

Changes to the changelog, now with more details:

All extensions files are now on a folder, just in case ;) :

Added typescript for future stuff (like the todo list)

Centered icon, i dont need to explain why (i hope)

Folding for nested if and every improved

Since we have ts, needed a .gitignore to exclude the out folder

Syntax highlighting, now evEry works too, and a few missing stuff like >

With ts, I added a new task to compile the extension before launching to make sure changes always are there and another option not to compile the extension, for example, just doing changes to the syntax hightlighting

The extension will only activate when you are editing a .sfm file or .sfml

Added 0.0.6 version on the vsce-versions
