Subject: [PATCH] Added a new option to set files associations in projects.
 Introduced a new configuration file for projects in the project file
 `.ecode/settings.json` file. Initially it supports files associations the
 following way: ```json { 	"files.associations": { 	
 "glob_pattern": "language_name", 		"functional": "cpp", 	
 "map": "cpp", 		"**/c++/**": "cpp" 	} } ```

Format is exactly the same as in vscode, and also, if no `.ecode/settings.json` file exists but does `.vscode/settings.json` file exists, it will fallback to that one.
This is related to the discussion in issue SpartanJ/ecode#585.
