[020] track builder bad behaviors

[Hagrud]

I create an issue to save all strange behaviors I found using the track builder in traincraft 020.

With minecraft rails:

• gravel and rails items fall when trackbuilder try to fill a lot of blocks

• when going down facing +x or -x the trackbluider dig vertically

With traincraft rails:

• trackbuilder fall instead of placing filler blocks

• trackbluider can place medium and large tracks but when there is an obstacle it use all of them without success

more than 15 medium tracks have been consumed by the trackbuilder to fill those two blocks

Others:

• Fixe break event related issues

Note for #482 you would need to put the filter for only taking the straight TC track in the track builder inventory/container class. there should already be a check if the item is a TC rail, so that can just be refined further.

Discord user report that trackBuilder does not trigger BlockEvent.BreakBlock Event, so there is strange interaction with world protection plugins:

• infinite block generation
• the builder may break blocks in protected area

I will try to fix this by reworking the digging process.
