add abort code (J3+) in install script, package

[JKoelman]

the thing is that the current code is not intended for Joomla 3 so it would be good to break of an install in Joomla 3 till we fully address it.

There is a check to "2.5" in script's preflight() function. Doesn't this work?
(maybe we should check $type to allow "uninstall" on each Joomla version?)

[JKoelman]

hmm, yes it works but was confused. was thinking that there would be aseperate install-script for the package but will close this one.

[Hoffi1]

Ah, now I understand. You mean the complete package. The script is for component only so maybe modules and plugins would be installed.
Mostly I install parts separately because on package I don't see messages from a part - maybe another todo...

So I think now we should keep it in mind - maybe for later.

[Hoffi1]

A package install script is possible, so we should add one.
I would also use this to automatically activate essential plugin(s).
So I can add the script incl. version check.
(We must ensure always both scripts require same versions. But I would not remove version check from component's script because one could install component only, without package.)

[Hoffi1]

Package now contains an install script which

• checks versions of Joomla, PHP, and MySQL
• checks if Magic Quotes are disabled
• checks for required PHP extensions
  as well as after installation
• clears cache (so Extension Manager should show new version information)
• activates (new) important jem content plugin

Now available on master branch.
