Currently Scry uses a huge amout of memory because the crystal compiler is embedded on it.
Scry analyze files every time a file is saved without checking if the file have been truly changed increasing even more the footprint (aprox. over 300 MB RAM on Linux)

Also maybe we can use external crystal processes instead of using require "compiler/crystal/**" ('cause, compiler is very heavy) I think using processes will free memory easier and improve Scry performance.

Also new features as types on hover and refactoring could be easier to implement.
