On drag over CM instance, call setDragCursor with event and 'editor'
string
Set ondragover function call upon this function too with folder/file
string, same as when init'ing via get branch
setDragCursor function added, handles cursor for dropping files editior,
folder and file including if we have the CTRL key down or not
No need to replace \r\n also in stitchChanges (\n and then \r will do
that).
If FTP based file, get from fixed filepath, explode on new lines and add
lineEnding to end of each but last, to match what the local file($file)
process will do.
Establish number of Unix and Windows lines in 'changes' update process
only (no need to do on new file) and also str_replace based on their
counts under FTP usage also (to match what local file processes are
doing).
When `$file` is a folder, the commands `filesize` and `filemtime` would result in the following warnings :
PHP Warning: filemtime(): stat failed for /var/www/html/css in /var/www/html/ice/lib/file-control-xhr.php on line 921
PHP Warning: filesize(): stat failed for /var/www/html/css in /var/www/html/ice/lib/file-control-xhr.php on line 940
This patch corrects this.
Wrapped `$ftpSite` in `isset()` where $ftpSite was a part of a condition for existence testing and was using the simplified mode for the check. The simplified mode resulted in the following notice being produced when no data was present in the `$ftpSite` variable.
> PHP Notice: Undefined variable: ftpSite in /var/www/html/ice/lib/file-control-xhr.php on line 518
While the error pertains specifically to line 518, this adjustment was applied to all condition checks on this variable.
Corrects the following error :
scandir(/var/www/html/ice/lib/../backups/localhost): failed to open dir: No such file or directory in /var/www/html/ice/lib/settings-common.php on line 190
(possible review required for if this is something that should be created before this method is called, or if a simple check as this patch does is all that is required.)
globalized $context inside `GetVersionCount()` to eliminate `Notice: Undefined variable: context in /var/www/html/ice/lib/settings-common.php on line 203`
Added check if file is readable for `.version-index`'s inside the loop within `GetVersionCount()`
