Symlink management rework

[JasonYao]

Description

Symlink management may be better by using a GNU tool, of which GNU Stow appears to fit the bill. Replacing Holman's linking function with this will thus future proof the script, and lower dependencies on outside code.

Features wanted

• [x] Allow for fast linking and delinking
• [x] Allow for dynamic linking and dynamic delinking (should not link things that we don't want to be symlinked, like setup scripts)

Using Stow

• [x] Allow for fast linking
• [ ] Allow for dynamic linking (should not link things that we don't want to be symlinked, like setup scripts) (possible via an ignore list)
• [x] Allow for fast delinking
• [x] [CON] requires another dependency to be installed
• [x] [CON] requires an ignore list in order to make it work properly, which is pseudo-dynamic at best

Current solution

• [x] Allow for fast linking
• [x] Allow for dynamic linking (should not link things that we don't want to be symlinked, like setup scripts)
• [x] Allow for fast delinking

[JasonYao]

Instead of using Stow, I'll proceed via normal bash to build out an automatic deletion script that will delete any symlinks in $HOME which point back to the dotfiles.

Automatic deletion function and uninstall script is added as of ad474a1cfaabdf97eb4b81c671fc56856dea02d1. Dynamic linking and unlinking is now complete
