Improve the way RadPageLayOut reacts to different view port sizes and make it consistent with the DeviceScreenSize detected with the Device Detection framework
As of now, the gutter (space between the columns) is hardcoded to 15 pixels. Perhaps we could have a server side property, say Gutters, that accepts an integer value and results in a generated class, say t-gutter-10. We can also have predefined styles, say 10, 20, 15 etc so the base variants are covered. If a developer wants, say 56 pixels gutter, it can be either set directly overwriting the styles or scoping trough the generated class t-gutter-56.
