Approve and Reject buttons should work just as the Add Translation one does

[xibe]

When translating, the Add Translation makes it easy to keep in the flow (and only use the keyboard) by automatically loading the next string in the current 10.

When moderating strings, approving or rejecting a string takes you back to the list of strings rather than open the next one. This breaks the keyboard flow (you have to click the Details link of the next string), which slows down the whole moderation process when having many strings to check at a time.

Approve and Reject should open the next string in line, just as Add Translation does.
