1. kor-table: fixed sticky header being scrolled up due to meeting with host bottom, now host has a height, which fits its content;
2. kor-input type='select': select's dropdowns with vertical scrollbars were made to look prettier - they have a padding from top and bottom, but don't have a padding from left and right, so the vertical scrollbar is placed on the right edge of the dropdown with some padding from top and bottom;
3. kor-input: fixed native browser input's popup which was shown for float values when step property was zero;
4. kor-input: implemented custom calendar popup for date and datetime types, which support all locales supported by the browser, a new locale property was added, in case it is undefined the browser default locale is used
