Support Prolog

[gokhansolak]

Hi,
Currently there is no Prolog support. I implemented Prolog support by adding a proper regex to config file at my local. However, there is an issue: Prolog uses the same extension (*.pl) as Perl. I guess, after my addition, Perl support is overwritten for pl files. It can cause confusion for users.

So I wanted to ask for suggestions. Should I commit my changes commented out, so users will uncomment it if they are interested? Or an option should be added to the settings page?
