CMakePM: Display CMake kit mismatch values in Settings page

updateFromKit() is now called on parsingFinished and the configuration
values that differ from the ones in the Kit's CMake configuration
will be displayed in red.

The "Initial Configuration" page will display the mismatches between
kit's CMake configuration and initial parameters.

The "Current Configuration" page will display the mismatches between
the initial parameters and the current CMake parameters.

The Tooltip is displayed with a bit of more space between values
for more readability.
