Fix borders for "Actions" column in Firefox

Added 'background-clip:padding-box' to "Actions" column
styling to make its borders visible in Firefox. Moreover,
since not every table has odd/even classes for its rows,
there still are some issues with border colors for a few
tables. This patch set adds 'background-clip:padding-box'
to each row style (not only to odd rows) to make borders
visible for every row, "Actions" column in Firefox.

Return eye-icon to its place when validation message is shown

Making eye-icon properly positioned relies on its parent having
'has-feedback' class - which makes the parent to obey 'position:
relative' and thus eye-icon with its 'position: absolute' is properly
positioned within it.
