Dropped motorbike won't start! Help?!

I recently bought a second hand Honda CG125, 2008 and everything has been fine - until now.
I did a stupid, put it on the stand on a hill and of course it tipped and fell onto it's right side (if you're sat on it).
There is some cosmetic damage and the front indicator bulb has gone, but the biggest problem is it won't start now!

Something leaked when it fell over (?), but I got it up with in a minute, didn't try to start it just rolled it in neutral into my yard.

Once in the yard I tried to start it and the engine rolled over and there was a loud ticking sound. I stopped, waited for a minute and then tried again and there was NOTHING - no ignition, no engine. I turned the bike off, did some quick googling and went outside to try it again, this time the electrics weren't working at all!

It's been an hour or two since now, and the electrics have started working again. The ignition is on a button, and when I press it the lights dim, but still absolutely no ignition or engine.

Any ideas what's happened? Is there any way I can get it started at home myself?
I am inexperienced with bikes, so please include details!
Help is GREATLY appreciated!
