Allow no icons & remove external icon resources

[karol-bujacek]

Hello Ales,

I’ve tried this nice app and I’ve noticed that icons are more-less required, at least I did not find possibility to not add any icon. Also links to font awesome resources are hardcoded in extrastyle block, base_site.html file.

Is it possible for you to add possibility to override these hardcoded resources and option to not include any icons intentionally (without magical guess)?

I would like this feature for internal / intranet / maybe even offline application where reaching external Font Awesome website may cause problems.
