Add-ons SVG Template by Xon 2.6.2

• Fix SVG template validation was broken which could result in preventing adding a language or style from working correctly (or rebuilding master data)

• Fix error running "xf:rebuild-master-data" when the exact template directory structure is missing and the SVG template is the first template compiled for that style.
• Fix possible compatibility issues with other add-ons extending SV/StandardLib's template helper code

• Fix template validation ran on the master style instead of the current selected style
• Fix for upcoming XF2.3 compatibility, as Doctrine Cache been documented as being removed.
