[TYPO3-dev] splitting localconf

[Steffen Kamper]

Hi,

while mirror a site to my local computer i got an idea and want to get 
some feedback from you.

There are mainly two parts in localconf:
* local conf (db-settings, im-settings)
* global conf (ext-settings, TYPO3_CONF_VARS - parts of it, etc)

What's about having a localconf.local.php which is included by localconf?
That would allow to overwrite the localconf.php by one of the online 
site without overwriting the local settings.

The cached file could merge both files, so there is no impact having 2 
files when cache is enabled.
