Code in place to allow removing source files from a project by right-clicking file in Project List/Files listview and selecting Remove File from Project on popup context menu.
A messagebox ill ask the user to confirm the desire to remove the file.

For iwb,eba, and asm files the corresponding ix* file will have the project entry removed (used to open project when file is opened if that IDE option has been selected).

When adding one of the above type files to a project the proper ix* file is created and the project's full pathname is added to the file.

With this arrangement a single source file can be used in multiple projects.
Also added code to prevent obj and lib files that have been added to the project from trying to open in the code editor when their entry is double-clicked in the Project List.
