B3 - Add ability to encrypt Origin C code

A new file type.ocz is introduced for easier Origin C code distribution. It is a C file but have the following differences:

• Password protected, so if you try to open it in Code Builder, you will need to enter a password. You can use option in this dialog to remember the password in the local user's registry for 30 days.
• OCZ files can be drag and drop into Origin for easy installation. It will not be added to system folder, but it will autoload so functions in such file will be available when Origin starts.
