Javadoc and Formatting fixes.
Also, extremely minor code changes which have been tested.
This commit is only part one of two commits that aim to fix problems with formatting in our project. In part two I will modify the Google Java Style Guide (since it closely matches our code style) for our project so there is guidance on how to format and document.
* Updated PlotSquared URL
* Removed plugin acronyms
* Fixed a typo
* Fixed grammar
* Use modern block id's
* Update YouTube video URL
Lazy tags means tiles/ents are not translated into the nms NBTBase until it is needed. Should be faster in cases where getFullBlock is called, but nbt is not always needed.
Commands like Copy and Paste, where the input/output are both nms worlds, can entirely bypass WorldEdit translating to and from the WorldEdit JNBT classes.
