INSTALL.md-Suggestions after successful build

[noestreich]

First, thanks a bunch for the effort you put in this project and for the detailed instructions. It worked out flawlessly for me and will supply my daughter with a great piece of easy-to-use hardware.
Hats off to you.

I just wanted to suggest a couple of minor-changes for the INSTALL.md-Tutorial, on passages which caught me off-guard:

• Installscript
  I did not see (or better: i missed) the well commented installscripts in /scripts/installscripts/ - maybe they ought be linked in the tutorial for their time-saving nature?

• Configuring lighttpd
  In the last step of configuring lighttpd, we set the rights for the shared-folder to make sure ist is accessible by the web server. But at this point in the build-process the folder does not yet exist. We are cloning the repo a couple of steps down the line. maybe the chmod-action should be placed under the "Install git"-section?

• Using a USB soundcard and changing the volume
  I made use of the linked stackexchange-article regarding the configuration of the usb soundcard via ~/.asoundrc.
  It worked without a problem. But after finishing up everything else, i was not able to set the volume via the Web-App.
  I had to edit Line 60 in /htdocs/index.php and replace 'PCM' with 'Speaker' - this might be helpful for others ordering from your proposed shopping-list (like i did). The line in question looks like this now:

  exec("/usr/bin/sudo amixer sset 'Speaker' ".$urlparams['volume']."%");

• PHP7
  Since we are living in PHP7-Times i used the following Line to install the php-dependencies

  sudo apt-get install lighttpd php7.0-common php7.0-cgi php7.0

  i can report, it all seems to work just fine.

Hi, thank you for these suggestions. I'll give them a try and will incorporate them in the scripts. And, true, sometimes there are tweaks that make it into the manual based on memory - never a reliable source ;)

I will leave this open for now, until I included your work.

@noestreich I fixed the inconsistency regarding the git install and chmod. I also changed the manual to support "php" in general and not "php5" (what was I thinking :). One thing where I could really benefit from your input:

Using a USB soundcard and changing the volume

If you take a look here: #20 it seems you are not alone with your tweaks. However, your's seems to be more general. Can you create a pull request for your solution (if it works globally) or give me a list of changes that I can add to the manual? Highly appreciated. Thanks.

Changed the install back to php5 after all, because the newer version with Stretch is in the making.
