Detecting and deleting dead scripts

[dldisha]

Issue Description

There are a couple of scripts in the codebase that seem to be dead code and don't have an impact on the development.

Fixes #1531

Changes Made

I have deleted all such scripts which are not being used for the development anymore. For resolving the issue, I first removed one script at a time and build the project again. If the build was successful without the script then that particular script is not being used for the development and is a dead code.

In total, I detected 7 such scripts that are dead code.

Thankyou @patricoferris for the review and the explanation. I'll study the scripts more deeply and get back to this asap.

grep was quite helpful :) Helped me to undersnatd a lot about the file system.

Coming to the issue, I think we may not remove ocamlapplet.bash too because it is linked to Makefile.common; a template file being used to generate certain configuration and run a certain task if something goes wrong with automatic config.
