Request: Textile support

[dawista842]

Textile is a markup language (like Markdown) for formatting text in a blog or a content management system (CMS). It is very simple language so implementation should be easy.

There are many implementations of Textile highlighting in other text editors and IDE's:

• Textile plugin for VS Code: https://github.com/idleberg/vscode-textile/tree/master
• Textile plugin for vim: https://github.com/timcharper/textile.vim
• Textile plugin for Emacs: https://github.com/juba/textile-mode
• Textile plugin for Brackets: https://github.com/svsudhir/Brackets-Textile-Syntax-Highlighter

so you can model yourself after these projects.
