core: add buffer local variable "completion_default_template" (evaluated) (closes #1600)

Browse Source 
When this local variable is set, it overrides the value of option
"weechat.completion.default_template".

It is evaluated, that means the global default template can be used to append
some custom completion. For example:

  /buffer set localvar_set_completion_default_template ${weechat.completion.default_template}|%(my_completion)
