hyperlink functions in Comments column

Previously, only the functions in the Command column were hyper-linked.
Also clarify the meaning of the "was" entries in the Comments column.
sync README.md with doc comments in elisp

The documentation in README.md was previously identical to that
in the Commentary section of use-package.el, modulo the following
differences:

  - No elisp comment ";; " prefix
  - Code blocks indented 4 columns not 2, as required by Markdown
  - Elisp symbols marked in backtick delimiters for monospace, not
    emacs backtick/forward tick pairs.

Unfortunately due to this duplication, sometimes only one of the two
files got updated, so they got out of sync.  This commit fixes that.

Fixes #46.
fix DRY violation by only having documentation in one place

The documentation in README.md was previously identical to that
in the Commentary section of use-package.el, modulo the following
differences:

  - No elisp comment ";; " prefix
  - Code blocks indented 4 columns not 2, as required by Markdown
  - Elisp symbols marked in backtick delimiters for monospace, not
    emacs backtick/forward tick pairs.

Unfortunately due to this duplication, sometimes only one of the
two files got updated, so they got out of sync.  With us all being
human, this is likely to continue to happen as long as the
duplication exists ;-)  Therefore since most users are likely to
encounter README.md before the elisp, and bearing in mind that
Markdown is a much more flexible format for documentation than
elisp comments (richer formatting, can be exported to numerous
other formats etc.), it is better to replace the docs in
use-package.el with a pointer to the README.md.

README.md: fix typo and punctuation
stop describe-personal-keybindings adding trailing space

When emacs is configured to highlight trailing whitespace,
the *Personal Keybindings* buffer looked pretty ugly.
This fixes that.

Merge remote-tracking branch 'YoungFrog/master'
Allow multiple forms after keywords

* use-package.el (use-package-mplist-get):
(use-package-plist-get):
(use-package-mplist-keys): new functions

(plist-get-value):
(use-package): use new functions

(plist-keys): remove function

The idea is to allow a modified kind of plist where keys are all
keywords that appear in the list, and values are the intermediary
elements. If a keyword is present but it's another keyword just after it
(like (use-package :defer :config (setq foo 'bar))), its associated
value will be t. If a keyword is not present, its value associated value
will be nil. Otherwise the value will be the list of elements between
the keyword and the next keyword.
