Auto detect language in code snippet

[benjo456]

Currently its required to manually select the language of a code snippet using the drop down menu.

Please add an 'auto detect' feature to detect which language to use based on snippet provided. This is similar to how Vscode is able to auto detect language via analysis of constructs used.

Prewritten libraries exist to achieve this, such as https://github.com/ts95/lang-detector
