PMV Test 1 HOTFIX

Okay so there were some ground bugs, they are now fixed!

- Fixed Upload song button not working

- Changed BPM and Song Duration input field text to white

- Now you can move on timeline by pressing spacebar even when song is not uploaded

- When uploading a grid in a naming format: {name}_{nr. of rows}_{nr. of cols}_{nr of frames} input fields are filled automatically

Also now you can upload videos to image gallery to make grids inside YAJOIG but it's not completly finished as it wasn't meant to be there right now. But you can use it (Although there are some bugs with seekbar and it needs few optimizations) press Shift + left/right arrow to move by one frame in video.

To the two of you who have bought bugged pmv test version. DM with some kind of payment verification and I'll give you fixed version for free as I can't reach you directly
