Context Menu Modifier for HTML and CSS files.

- This script adds or removes custom HTML/CSS template links for the
  "New" context menu entry in Windows Explorer.
 
 It works by modifying the following registry values:
 HKEY_CLASSES_ROOT\.html\ShellNew - FileName = "HTMLTemplate.html"
 HKEY_CLASSES_ROOT\.css\ShellNew  - FileName = "CSSTemplate.css"
 
 A base template file for each option is created in this location:
 %%APPDATA%%\Microsoft\Windows\Templates
 You can manually edit these files to customize them as needed.
 
 PLEASE CREATE A RESTORE POINT BEFORE USING THIS SCRIPT!
 It is strongly recommended to back up your system (restore point,
 registry export, or full image) before making any registry changes.
 This takes only a few seconds and can prevent any potential regret.


 - You can open this script in a text editor and modify the registry
   commands or create your own custom versions.
 - If you are unsure about any change, search online for guidance.
 - Editing the Windows Registry (regedit.exe) can cause problems if
   incompatible changes are made, though following instructions usually
   results in only minor registry bloat.
 - This version (v1.0) does not yet support adding fully custom templates.
   That feature will be added in a future update.
