Library 1.5 Specification should be more clear about Keywords

[jbdatko]

The Library specification for 1.5 is not very clear concerning "keywords" and simply says the following without any link:

The list of highlighted keywords must be placed in a file called keywords.txt. The format of this file is the same as the 1.0 libraries

I did not realize this meant keywords for _syntax highlighting_ until I found this blog post.

I recommend adding a statement about syntax highlighting and/or linking to the 1.0 keyword semantics.

Is this not clear for you? If so, why not edit it? It is a free wiki and it seems you are allowed to edit.

Keywords

The list of highlighted keywords must be placed in a file called keywords.txt. The format of this file is the same as the 1.0 libraries

Servo/keywords.txt

I have no problems editing the wiki and I probably just should. However, I wasn't sure of the workflow. I figured it'd be nice to have an issue to reference the "why" behind the change.

I'll edit the wiki, link the editing text back here and then close the issue.

Hi to all! Arduino has a new theme so all the keywords should be updated according to this
