Bug/Issue Odd characters in .json files causing exceptions on warp.

Hello all! I was experiencing this bug on my 100% vanilla run and my Frackin' Universe run as well and thought I would share my fix for the next version of Starbound.

OS: Slackware64 14.2
uname -a: Linux Water 4.4.14 #2 SMP Fri Jun 24 138:27 CDT 2016 x86_64 Intel(R) Core(TM) i7-7700 CPU @ 3.60GHz G
enuineIntel GNU/Linux
glibc: 2.23
Starbound: 1.3.2

Steps to reproduce:

1. Go to planet
2. Try to warp down
3. If planet has one of the certain dungeons you end up back on your ship

In the console this is produced (landing in a 'Aether Sea' planet in FU, but similar happens in vanilla):

I unpacked 'packed.pak' and edited ./dungeons/hylotl/hylotlcity/hylotlcityhousesmall3.json where there were 3 characters in the whitespace that shouldn't be there. Here's my diff is attached.
After repacking the tree and backing up the original packed.pak I restarted the game and was able to go to the planet successfully with no odd output in the console.

I grepped the tree for xE020 and found the following files affected:

Hope this helps people with a similar issue and gets fixed in 1.3!
