Path aliases now resolved at build time - Fixed while/for loops not working properly

Changelog:

• Path aliases were previously resolved at runtime, using module-alias. However, it didn't resolve in declaration (.d.ts) files, leading to incorrect type inferring. To solve this problem, Sandstone now uses a new Typescript compiler, ttypescript. It allows the use of compiler plugins: Sandstone uses the typescript-transform-paths plugin, which resolves all path aliases at build time.
• While/for loops weren't including the run keyword inside the recursive function. It is now solved.

Small improvements

Changelog:

• Selectors predicate field now directly accepts a predicate
• Selectors scores field now accepts +Infinity and -Infinity when specifying boundaries. Example: scores: {deaths: [1, +Infinity]}
• Fixed getName being not accessible on mcfunctions
• Function tags now directly accept mcfunctions

Fix recipes not being saved in the correct folder

Recipes were saved in the "recipe" folder, instead of the "recipes" folder. This release fixes this.
