Handle invalid paths better

Currently the user can enter any string as a minecraft directory

This is fine, but we should ensure we are better able to handle this

if it aint a directory we should put up a warning

also we need to check if they have the minecraft version installed and launched, just realized taht it doesnt have that either

are there any other sanity checks on what makes a valid minecraft directory? i guess launcher_profiles.json?

[LeafHacker]

Well, if they've not run the launcher before we may need to create launcher_profiles?

[LeafHacker]

Do they definitely need to have run the mc version before?

[leijurv]

Yes the definitely need to have run it (#33)

When you edit that JTextField it doesn't update the actual setting tho =(

My bad, atm you have to hit enter for it to update the setting. If we handle invalid stuff better we should probably listen on some typing event instead of ActionEvent.
