List of changes
+ Handling information about a tool has been improved a lot by providing a `HackingTool` class, which takes care of showing the options, running the selected option, executing the required commands
+ This class is designed with flexibililty and simplicity in mind, so adding a new tool is a lot easier, mention TITLE, DESCRIPTION, list of INSTALL_COMMANDS, RUN_COMMANDS and PROJECT_URL and there you go...
+ grouping all the `HackingTool`s is also made super simpler by providing a `HackingToolsCollection` class which groups the tools into their respective categories. Just add the instances of `HackingTool` classes to the TOOLS property of the `HackingToolsCollection`.
+ Refactored all the tools into separate files based on their categories.
+ Added a READM_template.md and generate_readme.py script to automatically generate Table of contents and the list of tools available automatically.
+ Now each tool in the README.md points to its project url if provided. This makes it easier to visit the project from the readme.
