Update to 3.4.00

Changelog:

Version 3.4.00
==============

- The english.5 manual page has been dropped from the distribution;
  the english.aff file provides superior documentation (and in any
  case, most people will use munchlist to apply affixes).

- Ispell now supports systems (BSD) that foolish discarded backwards
  compatibility and insist on using termios.

- A function (getline) has been renamed in correct.c to solve
  compilation problems on some systems.

- The manual page now correctly identifies the ispell version that it
  describes.

- It is now possible to insert the ispell version information into
  shell scripts via the Makefile.

- An error has been corrected in the English affix files that caused
  certain words ending in "th" to be pluralized incorrectly.  The
  dictionaries have been updated to ensure that no incorrect plurals
  have crept in.

- The personal dictionary is now written in a stable order when there
  are multiple variant capitalizations of a word.

- The security of temporary files has been improved on systems that
  don't have the "mktemp" command.

- The deformatters makefile has been changed to be compatible with
  older versions of make.

- A bug in TeX deformatting has been corrected.  Previously, two
  adjacent math-mode environments introduced with dollar signs, such
  as $a=b$$c=d$, would cause ispell to lose track of whether it was
  in math mode.

- The Makefile now supports a DESTDIR installation prefix (patch from
  Petter Reinholdtsen)

- The American and British Makefiles have been simplified to ensure
  that dictionaries are always built with the lastest information.
