[TYPO3] Typo3 coding standards

methods exec_* are the way to go if you want to be compliant to TYPO3 
standards. But they read data from the TYPO3 database. If you need to 
read other databases from your extension, you should use play with 
extension ADODB and should be able to use exec_* functions for your own 
extension reading/writing from/to another database. I did not have time 
to use them a lot but including PEAR packages for MSSQL for instance or 
writing again all mysql() statements yourself is definitively not a good 
thing to do except for experimenting stuff before writing cleaner code.

Open install tool and check that config is OK and that image 
manipulation is OK too. You'll certainly need:

- gd
- iconv/mbstring

and perhaps other to let Extension Manager be able to download packages 
successfuly, I do not know and did not check, I always activate Curl.
