Checks all ICEcoder files are writeable and therefore moveable, before
proceeding with the update.
If it files any that aren't, it will display a message, list them and
die with a link back to ICEcoder.
Also ignoring .git dir
No longer using 3 hardcoded examples in array, but scanning the old dir
and updating files beginning 'config-'. That covers the .php and old
files also.
$context added as global so we don't get undefined
transposeSettings function added as sub function we can all with params
copyOverSettings is now a function which calls that sub function 3
times.
Coping over system settings now won't set line if $thisKey is blank
2 more functions added to copy over users template and users settings
files. These are largely the same as copying over settings, so will make
a sub function and call will params as a next step.
Gets old and new settings info, counts through each line of new settings
and if we have a match on the old settings, copy that over if it's not
versionNo or codeMirrorDir.
Saves settings once the $content is established
$updateDone = true moved to end of new function, copyOverSettings
Extra echo line in openNewZip and then calls this function
Get settings from old config___settings.php file
For now, for each one, get $key and $value
Need to save these info new config___settings.php file
Stores old versions with timestamp in dir name
Copies new version into a new dir
Detects & downloads the latest zip file
Unzips and if all went well, directs to the new version
Provides info on it's progress and also a message if things go wrong
