Improved main site design and easier personalization

The main site design is now faster to load and includes different new features and improvements and also it can be easily personalized from the administration panel by changing its colors (select one of the predefined colors or by entering a custom color code) and home page slider. For the slider the administrator can choose the content-if the slider should show the last jobs or the featured jobs or own slides, upload and set the background images, choose the text animation and others.
