A simple template manager, load a config file and parse it into a map of named templates for use in rendering pages.

Read in a config.json file of the format:

{

"root":  #the root template, all templates are compiled by cloning this files parse

"tpldir": #the root dir of the templates

"helpers": #array of filenames, compiled into root (css.tpl, js.tpl, etc...), optional

"tpls": # array of template definitions

	{ #template example

		"name": #the name you want to refer to this template by

		"files": #files to compile into root

	}

}

See tplm_test.go for an example of a config file.

Don't currently support adding functions to the templates.
