Polish touch controls

[Hachitus]

We use hammer for touch controls currently, but it doesn't seem to work as well as it should currently. I do not know if the issue is some native timeout in mobiles or if the hammer library has some issue or possibly some configurations we use setting up hammer is wrong.

Now when you test it, when you select units by pressing them on mobile, it doesn't always succeed. When the touch is not totally accurate or too soft, it might fail. Or if you move your finger while pressing it might cause issues too.

I tested this with my 3 year old daughter, who got the issue quite fast :D.
