MMM-Pages readme section clarification

[edward-shen]

excludes is actually a byproduct of how MMM-pages hides modules:

MM.getModules()
  .exceptWithClass(this.config.excludes)
  .exceptWithClass(this.config.modules[this.curPage])
  .enumerate(module => module.hide(
    self.config.animationTime / 2,
    { lockString: self.identifier }
  ));

Since exceptWithClass basically acts like a filter, I was thinking of the config option as an exclusion filter, ergo excludes. You're right though, the name leaks implementation detail, and it doesn't make much sense for end users. I've changed it to fixed (while still supporting excludes) to hopefully help people with this. No real action is required by you, unless you want to use fixed instead—this issue was just an FYI.

Sounds good! I'll update the README with this information.
