Add a better link to lua-mode in the README

Instead of linking to EmacsWiki it is more helpful to link directly to
the website for lua-mode itself.  This patch also removes the
incorrect statement that lua-mode comes with GNU Emacs; it does not.
Implement and document love/search-forums

This provides the love/search-forums function and binds it to the keys
‘C-c C-f’, allowing users to search the official forums from Emacs.
Add ‘Search Forums’ to the command menu
Merge branch 'search-forums'

* search-forums:
  Add ‘Search Forums’ to the command menu
  Implement and document love/search-forums
Change the key-bindings to avoid conflicts with lua-mode

No key commands in lua-mode begin with ‘C-c C-o’ so this patch changes
love-minor-mode to use that prefix.  This fixs the conflict over ‘C-c
C-f’ and hopefully will prevent future conflicts.
Link directly to the license from inside the README
Bump the version to 1.1

This latest version includes the ability to search the LÖVE forums and
fixes conflicts with the key-bindings in lua-mode.
Fix a small error in Markdown formatting in the README
Fix a typo in a key-binding in the README
Fix the regular expression for whitespace in love/search-forums

We need to replace whitespace with plus signs for the URL we create.
The code attempts to match whitespace using ‘\\s+’ but this is not
correct.  Emacs uses ‘\\s-’ to represent whitespace, so the function
needs to use ‘\\s-+’ instead.
Rewrite love/automatically-enable to use save-excursion

This is a better approach since the function uses goto-char to jump to
the beginning of the buffer to search for LÖVE functions.  There is a
chance a user may open a Lua file through a bookmarked point, for
example, so in that case we would not want the existing behavior of
moving the point to the start of the buffer.  By using save-excursion
we can avoid this potential problem.
Rename love/automatically-enable to love/possibly-enable-mode

This name is more accurate since the function will not always enable
the minor mode.
