Add settings system info and update layout with lang lookup

PR includes the following changes:

1)	Layouts->default.blade.php
2)	Settings->edit. /index.blade.php
3)	Lang->en->admin/settings/general
4)	DB migration file-> 2014_08_17_070015_add_sysinfo_col_to_settings

- Removes the incorrect version number text from the master template (bottom right)
- Adds additional db settings column ‘showsysinfo’
- Adds additional “system information” section on settings view
- Adds showsysinfo check box on settings edit
- Updates layout and formatting of settings->edit to match view page
- Changes all ‘settings’ edit/view text items to language lookups

* in some cases we noticed ‘@lang(edit)… “Settings” style button labels.  We would like to change these to specific @lang(edit_settings) language lookups as the wording for "settings" is different in some contexts also in some languages the noun comes before the verb instead of after, as in English.
