* txr.c (version): Bumped.
* txr.1: Bumped version and set date.
* configure (txr_ver): Bumped.
* RELNOTES: Updated.
* txr.vim: Handle : symbol properly.
* eval.c (op_defun): Bugfix: documentation says that defun supports
the same parameter list as lambda, and that is the intent. But
this was broken, since op_defun was expecting the parameter list
to be a proper list containing only bindable symbols, ruling out
the use of the consing dot for rest parameter as well as the colon
keyword symbol for optional parmeters.

(eval_error): nostatic added to suppress a g++ warning.
(dwim_loc): Takes new value as the original unevaluated form so
it can control evaluation. Support for del operator added.
(op_modplace): Bugfixes: new value form was being unconditionally
evaluated and out of order w.r.t. other forms. Now there is
left to right order. The form is evaluated later, since for most
operators it is on the right, with the exception of push.
dwim places can now optionally control the evaluation of newform.
del operator supported in gethash case as a special case.
error case added for del: if it's not handled in gethash or
dwim_loc, it is an error.
(eval_init): del_s initialized, and del operator added to table.
* txr.vim: syntax highlighting for del.
* txr.1: Documented del.
