Template administration and optimization

Automatically disable Joomla Bootstrap JavaScript without "JUI Disable" plugin.

Added the following options under "Advanced" tabs:

• Load Template Local Files (default YES), allowing admins to use local or CDN files. This also disables Joomla Core JQuery in order to prevent conflicts.
• Joomla Meta Generator (default DISABLED)

New tab "Disable J! Files", includes the following checkboxes:

• J! Core files. If checked, disables all Joomla cora assets
• J! Bootstrap JS File. If checked, disables only Joomla Bootstrap JavaScript
• J! Caption. If checked, disables only Joomla Caption JavaScript
• J! Core JQuery File. If checked, disables only Joomla JQuery JavaScript
• J! Core JQuery Migrate File. If checked, disables only Joomla JQuery Migrate JavaScript
• J! Core NoConflict File. If checked, disables only Joomla JQuery NoConflict JavaScript

I also created helper.php in order to keep index.php cleaner with the new options.

Hi @Dade88 ,
thanks for your pull-request.
In the meantime I updated to Bootstrap 4.1.3, too. The "Autocomplete" update made me think. In the end I removed it completely to just use it from JUI.
I'll have a look at the template admin changes after version 1.11 together with the changes proposed in #26.

You welcome, nice to see you @jwiesel :)

I'd like to make more changes to the back-end in the future (for example, ability to pick FontAwesome 4 -default - or FA5), but I tried to make the more urgents - at least to me - changes on this one.
