[Fix #720] Install system packages using system-packages-install

:ensure-system-package was installing packages by running
system-packages-get-command via async-shell-command. This meant that
system-packages-use-sudo wasn't being honoured.

This patch makes :ensure-system-package use system-packages-install
for all cases, except where a custom install command is supplied, in
which case async-shell-command is used.

This issue was introduced in 7303e89 [#673], as a fix for
[#661]. Prior to that commit, system-packages-use-sudo was being
honoured.

This patch also fixes a bug where a cons containing a lone symbol in a
list of conses causes nil to used as the package to install.

Correct prefix keys after use-package-autoload-keymap

allow :ensure-system-package to check the presence of files at path

closes #660

Place :chords at beginning of use-package-keywords

When it is at the end, the keys don't get bound until after the package has been loaded, which is bad.  Placing it at the beginning allows the key bindings to be mapped to auto-loaded functions before the package is loaded, so that a key chord press triggers the package load.

New style of auto-deferral for chords

Enable lexical binding

This supercedes #617 and closes #648

Added an Introduction taken from the README

Update debug info in readme

This resolves #626.

By adding events of the form (cons t event) to unread-command-events, Emacs
correctly updates this-command-keys for the subsequent use of the prefix.

Before this change, packages like my which-key were not getting the correct
prefix after use-package-autoload-keymap loaded the relevant package.

See justbur/emacs-which-key#192

ensure-system-package cleanup

The function introduced in #673 wasn't declared at compile time, and
it made byte compiler unhappy. Moreover, it was forgotten to remove
redundant compile time variables. Thanks @tarsius for pointing that
out.

This change
* Removes redundant variable declarations
* Adds `system-packages-get-command` function declaration.

new use-package logo

1. Added new use-package logo files:

- Overwritten existing .png files with new .png files in static folder
- Overwritten existing .ico file with new .ico file that has multiple
dimensions (16x16, 32x32, 48x48)
- Added img folder
- Added svg-file that will be used as main logo to img folder
- Added the logo source files to /img/logo-raw folder if any changes are needed
in the future

2. Change config.toml

- Added param favicon to force load the new favicon and not a cached one
- Changed logo path to img/use-package-logo-96x96-v1.svg

Document that remapping commands is supported with bind-key

[Fix #661] ensure-system-package: honor system-packages customizations

ensure-system-package doesn't honor system-packages
customizations (#661), because system-packages didn't provide an API
to retrieve shell command to be executed.

This change makes use of the new system-packages'
`system-package-get-command` function and therefore fixes the issue.

Add info about auto-package-update to the README

When I first read the README, I assumed that :ensure kept packages up-to-date.
It is very unclear about this. Having discovered that it doesn't, I found
auto-package-update, which seems to do this job just fine.

Add missing parenthesis

:ensure-system-package - allow cdr of cons to be a package name symbol
