Change default web-font "Lato"

[AlexWaha]

Need to change default web-font "Lato" to other font, as sample "PT Sans or OpenSans or Roboto", because "Lato" doesn't support cyrillic symbols.

And disable font check in app/controllers/AuthController.php line 302 $font = 'assets/css/fonts/Lato-Lig-webfont.ttf'; // Path fot ttf file - That's not right! Maybe need to use default font (Tahoma or Arial)

It's very important!
