fix #25
fix: make ask-if-create work

using unless, nothing occurs. simply bug.
fix: bug by typo
fix: set vars running setup function

before, though the setup function changes defvar setting,
it doesn't set var value at that time. so make it being set.
add: hcsm-template-path in var-settings
add: file initialize

hcsm-fileinit.el is called in hcsm-folderinit.el
load hocsom/templates/tex/* and save in folders as its proper name.
but replacement inside folders is yet to be implemented.
