tildify.el: introduce a `tildify-pattern' variable

Browse source 
* textmodes/tildify.el (tildify-pattern): New variable for
defining tildifying pattern.  Being a buffer-local variable it is
much easier to handle than `tildify-pattern-alist' that has been
used so far.  It also works better with derived modes.
(tildify-pattern-alist): Mark as obsolete.

* textmodes/tildify.el (tildify-pattern, tildify-space-string):
New variables for specifying tildify pattern and representation of
a hard space -- a no-break space by default -- respectively.
Being buffer-local they are much easier to handle than
`tildify-string-alist' and `tildify-pattern-alist' respectively
that have been used so far. They also works better with derived
modes.

* textmodes/tex-mode.el (tex-common-initialization): Set
`tildify-space-string' variable in all variants of TeX mode since
