Template engine PoC

Things to consider:

• Needs additional chmod of cache dir - 775
• ClonOS version is taken from the Config static class and not the version file
• I ve removed warning for IE as it now works OK

I would like to take it after the FreeBSD 13.-RELEASE, when I plan to update the image of the ClonOS. As it can affect places that are already well tested

[bozhinov]

That's perfectly fine.
