[TYPO3-core] RFC #14719: Automatically create ENABLE_INSTALL_TOOL file when 1-2-3 Install Tool is used

[Jeff Segars]

Hey guys,
Thanks for all the feedback so far.  Here's a quick recap of the various 
options, as well as the pros and cons of each.

1. Create ENABLE_INSTALL_TOOL as part of 123 Install Tool redirect
Pros: simple, very easy for user
Cons: security issues, the Install Tool remains accessible until there's 
a DB configured regardless of how long that may be

2. Ship with an ENABLE_INSTALL_TOOL.1 file
Pros: no security concerns, a little easier for user
Cons: timestamp does not change when file is renamed so there has to be 
some code component

3. Improve the lock message when in 123 Install Tool
Pros: no security concerns, the file creation is more clearly explained 
and less "scary"
Cons: the file still has to be created manually

Anything else I'm missing?

Thanks,
Jeff
