- Improved CLI Interactive readline shell (Johannes)

  . Added cli.pager ini setting to set a pager for output.
  . Added cli.prompt ini settingto configure the shell prompt.
  . Added shortcut #inisetting=value to change ini settings at run-time.
  . Don't terminate shell on fatal errors.

A pager can be a an shell command which will receive the command output on its
STDIN channel

php > #cli.pager=less
php > phpinfo();
(output will appear in the pager)
php > #cli.pager=grep -i readline
php > phpcredits();
Readline => Thies C. Arntzen
php > #cli.pager=
(output appears again direct on the terminal)

A prompt can contain a few escape sequences like

php > #cli.prompt=\e[032m\v \e[031m\b \e[34m\> \e[0m
5.3.99-dev php > //Colorful prompt with version number

A prompt can also contaian PHP code in backticks

php > #cli.prompt=`echo gethostname();` \b \>
