Created new function levelUpAllPrereqSkills()
It does exactly what you should expect. Modified the plus button to call this function if you attempt to level up a locked skill. Now it will allocate points to all your pre-reqs for you, so you don't have to click on all your pre-reqs to learn a level 50 skill. It will be done for you.
TODO: Remove the brightness(20%) filter. It is no longer needed to show the user that they can't allocate points to that particular skill. Since now, it is possible to level up any skill.
