Meta viewport correct syntax

[Hagith]

Fixed meta viewport syntax.

WebKit browsers (Chrome, Safari) do not accept semi-colons in meta viewport content definition.

Chrome console errors:

Viewport argument value "device-width;" for key "width" not recognized. Content ignored.
Viewport argument value "1.0;" for key "initial-scale" was truncated to its numeric prefix.
Viewport argument value "1.0;" for key "maximum-scale" was truncated to its numeric prefix.
Viewport argument value "0;" for key "user-scalable" was truncated to its numeric prefix.
