template: delete old template code.

It's already in old/template; make that build.
Update a couple of references to point to the old template.
They can be updated later.
Update goplay to use exp/template.

-/*
-	Package template implements data-driven templates for generating textual
-	output such as HTML.
-
-	Templates are executed by applying them to a data structure.
-	Annotations in the template refer to elements of the data
-	structure (typically a field of a struct or a key in a map)
-	to control execution and derive values to be displayed.
-	The template walks the structure as it executes and the
-	"cursor" @ represents the value at the current location
-	in the structure.
-
-	Data items may be values or pointers; the interface hides the
-	indirection.
-
-	In the following, 'Field' is one of several things, according to the data.
-
-		- The name of a field of a struct (result = data.Field),
-		- The value stored in a map under that key (result = data["Field"]), or
-		- The result of invoking a niladic single-valued method with that name
-		  (result = data.Field())
-
-	If Field is a struct field or method name, it must be an exported
-	(capitalized) name.
-
-	Major constructs ({} are the default delimiters for template actions;
-	[] are the notation in this comment for optional elements):
-
-		{# comment }
-
-	A one-line comment.
-
-		{.section field} XXX [ {.or} YYY ] {.end}
-
-	Set @ to the value of the field.  It may be an explicit @
-	to stay at the same point in the data. If the field is nil
-	or empty, execute YYY; otherwise execute XXX.
-
-		{.repeated section field} XXX [ {.alternates with} ZZZ ] [ {.or} YYY ] {.end}
-
-	Like .section, but field must be an array or slice.  XXX
-	is executed for each element.  If the array is nil or empty,
-	YYY is executed instead.  If the {.alternates with} marker
-	is present, ZZZ is executed between iterations of XXX.
-
-		{field}
-		{field1 field2 ...}
-		{field|formatter}
-		{field1 field2...|formatter}
-		{field|formatter1|formatter2}
-
-	Insert the value of the fields into the output. Each field is
-	first looked for in the cursor, as in .section and .repeated.
-	If it is not found, the search continues in outer sections
-	until the top level is reached.
-
-	If the field value is a pointer, leading asterisks indicate
-	that the value to be inserted should be evaluated through the
-	pointer.  For example, if x.p is of type *int, {x.p} will
-	insert the value of the pointer but {*x.p} will insert the
-	value of the underlying integer.  If the value is nil or not a
-	pointer, asterisks have no effect.
-
-	If a formatter is specified, it must be named in the formatter
-	map passed to the template set up routines or in the default
-	set ("html","str","") and is used to process the data for
-	output.  The formatter function has signature
-		func(wr io.Writer, formatter string, data ...interface{})
-	where wr is the destination for output, data holds the field
-	values at the instantiation, and formatter is its name at
-	the invocation site.  The default formatter just concatenates
-	the string representations of the fields.
-
-	Multiple formatters separated by the pipeline character | are
-	executed sequentially, with each formatter receiving the bytes
-	emitted by the one to its left.
-
-	As well as field names, one may use literals with Go syntax.
-	Integer, floating-point, and string literals are supported.
-	Raw strings may not span newlines.
-
-	The delimiter strings get their default value, "{" and "}", from
-	JSON-template.  They may be set to any non-empty, space-free
-	string using the SetDelims method.  Their value can be printed
-	in the output using {.meta-left} and {.meta-right}.
