Plugin/Theme installer: Do not bail if empty destination directory exists
|Reported by:||dd32||Owned by:|
At present, If you attempt to install a plugin or theme, and the destination directory already exists (Say from a failed upgrade), Then the installer will bail.
Patch adds a check to simply use the folder if it exists AND is empty.
However, It still counts hidden files as being a item in a directory, so if a .svn folder or .htaccess file exists in the folder, the installer will bail. - Any thoughts on that? Should it continue if there are only hidden files? I'm thinking not at present.
