HELP! My Minecraft Crashes!?

OK, so I'm making a Minecraft mod in Minecraft version 1.5.2 in Eclipse. Currently I have tonne of items there (I'm a begginer in modding so I do not have any complex codes). While I added some new Items/blocks I always played my Minecraft to check it and it did work. Today however using the same code I added about 10 new Items and when I pressed "Run" a crash message showed up saying "Failed to start game!...illegal object naming null". I used to get it earlier about 2-3 times but that was long ago and because of the stupid mistakes. Currently all my codes are perfect, all imports are imported and Eclipse doesn't show any errors. PLease help, as I said I'm only a begginer in Forge modding therefore a person who knows it better than me should be able to solve this issue. I will present the error message and my base java file in which I have all the codes in the download below (can not place them here as I do not have enough space).

PS: does anyone know how to create a block with more than one texture? ex. Crafting Table, Furnace, Wood, e.t.c.
