Install prnMsg not displayed

[apmuthu]

The install/index.php file makes an initial check for the config.php file and is expected to exit after displaying a message. The function prnMsg() merely appends the message to an array to be displayed at the end of the script, but the very next statement is exit; which makes sure that the script gets truncated thereat.

Hence, replace line 156 of install/index.php:

		prnMsg(_('It seems that the system has been already installed. If you want to install again, please remove the config.php file first'),'error');

with

		echo _('It seems that the system has been already installed. If you want to install again, please remove the config.php file first');

Furthermore, if the database exists and no tables exist in it, then, the script should be allowed to skip over db creation and config.php creation and proceed to database table creation.

I have done the change on the error message, and pushed the commit.

I will need to think how to do the other change you suggest.

@andrewcouling thinking about this there are a number of places in the installer where prnMsg() is called, and as header.php and footer.php are never used then the messages won't get displayed using the new system. Is it worth having a prnMsgInstaller() function?

All prnMsg have been replaced with echo statements in the install/index.php file.
