New icons for elementaryPlus (merging request)

[sergioad]

Hi friend could you check and try my modifications of the elementaryPlus icon theme? I made it because I wanted to have the most complete elementary theme, if you liked it could you merge it with the official elementaryPlus? if you want I have added the original sources to let you experiment with them :)
