quadrant updated to 1.15! New level-making guide!

Hi everyone! Sorry it's been such a long time since I last released something, it's been an exciting month for me. I got married and showed quadrant on a huge music festival (fusion) in Germany. Unfortunately I still haven't gotten uploading of workshop items working... :/ I'll spare you with the technical details, but I can tell you that implementing Steam stuff is a pain. So what's new in 1.15?

• Non-widescreen aspect ratios look far better now! (No black bars anymore)

• Lots of optimizations - The game should run smoothly on pretty old computers now. (Got it running at 60fps on a Raspberry Pi 2B)

• Fixed annoying bug repeatedly congratulating Sonic Boom achievers. (Some people now almost always stay under 6s in speed mode...)

• Made credits easier to read.

• Lots of small tweaks and fixes.

Ok, so maybe these updates don't matter to most of you, but that's not all! I wrote a guide which should help people to get into making levels. I'll be flying to Kyoto for BitSummit in about 11 hours, so the workshop will probably not be live for a while. But I'll try to get it done as quickly as possible! Cheers! undef
