Capabilities check not working due to array_flip

[screambeard]

In the ToolProvider class a check is made on the capabilities.

Line 895 states the following:
if (!in_array($name, $capabilities) && !in_array($name, array_flip($capabilities))) {

However the use of array_flip in combination with == in line 895 causes every capability to pass, since string == 0 is true (see link)

Either remove the array_flip part, since I don't think it is needed.
Or make it a strong comparison: ===
