Created form for initial setup

Will add connection credentials if connect.ini DNE

Get Root MySQL credentials for creating user/database
Get basic <head> info (title, description, etc)
Created initial form
Do not use pointers for quote() & escape()

Using pointers forces use of variables, which is not always what we
want here. Just return.
Nearly complete on install form handler

Creates user and sets up database. Multiple notifications along
the way if something goes wrong.

Need to add site specific information to head, such as author, title,
etc.

Also, need to create a default user.

Lastly, the default database needs to be created. Tested and working
with
a mysqldump of my actual database, but one needs to be created with some
Lorem Ipsum and such.
Merge branch 'issue_15' into dev
Merge branch 'master' into dev

Conflicts:
	components/forms/install.php
Accidentally worked in master instead of issue_15

Nearing completion of issue #15!
Ignore *.orig

These files result from merge conficts. I see no reason to include them.
Form should be complete now

All <fieldset>s no in <detail>s.

Added <fieldset> for head, with all currently used names set, and an
appropriate input type for each. Required inputs are set as required.
Just log the inputs from install form

Keep everything in place, but do nothing but log it for now.
Default database as a mysqldump

Contains no `users`, no `head`, and only some Lorem Ipsum for `posts`
Added validators for email & URL
Require login for 'test' case
Added patterns and made root password optional
Added some validation to install form handler

Use is_email(), is_url(), empty(), preg_match(), etc as needed
Validation for $_POST['install']['connect'] too

Need to determine a way of distinguishing between not set and not valid.
Include ['connect'] validation with the rest of install form
Use radio instead of checkbox for robots.
Resolve issue #21

Still needs documentation and has a few bugs to work out, namely
reverting changes if not successful, but database is being created,
user is successfully set up, and site info is being set to `head`.

Will file another issue for further enhancements, but consider this
complete.
get [head][title] from parse_url()['host']

Might be better to use a $_SERVER var. When do they differ?
Use parse_url() in hopes of making code clearer
