True/false blockstates require quotes in order to use them in entity nbt

Now that the output log isn't getting flooded by command block errors, I realized why this problem was happening. For example, when you write a command that goes something like this:

/summon falling_block ~ ~ ~ {Time:1,BlockState:{Name:lever,Properties:{face:floor,powered:true}}}

Then the powered part of it will fail due to being "unable to read the value" of that property, unless you surround the value with quotation marks. According to the log, it's apparently automatically converting the words true and false into 1b and 0b respectively, which aren't valid blockstates. This occurs for other true/false blockstate arguments as well, such as open, and all of this also applies to the blocks being carried by endermen and minecarts.

I'm not sure if the auto-conversion is deeply-rooted and hard to fix, but that seems to be the only problem here. And as mentioned, quoting will allow the state to work properly, e.g. open:"true", so it's not too major of a problem.
