[TYPO3-english] Is 50 "Include basis templates" max and if so how do I raise that number?

Thanks Dmitry.

I am able to find the line responsible for the configuration through the 
configuration tool.

$TCA['sys_template']['columns']['basedOn']['config']['maxitems'] = 50;

But I am unsure where I actually edit this line?

I have been looking through the files in the t3lib/stddb folder, but with no 
luck.

Any suggestions?
