Text overflow improved

* OTUI property "text-overflow" now takes 2 values "length character" (eg. "text-overflow: 13 [...]" will result in cutting long text and adding [...] at the end)
* OTUI property "text-overflow-length" takes number value to cut text that is longer than the value
* OTUI property "text-overflow-character" takes string value and adds at the end of overflowed text, default is "..."
* Updated container style with new property
