Make CedarLogic always a stand-alone executable

[JoeHCQ1]

Is your feature request related to a problem? Please describe.

The installer requires NSIS which is otherwise unnecessary and I expect Windows-specific. Would be great if we could remove anything we don't need and also make it easier for cross-platform use. Also, file extensions are only prescriptive in Windows. The Unix-based world considers those just suggestions.

when in doubt, leave it out - Hints on Computer System Design

Relates to #57

Joe ... I've seen a lot of activity on this an other issues and have noticed your responsiveness to the developers. So I just wanted to express my thanks again for your work in making CedarLogic better. Your efforts to the project have been a Godsend.
