Fixed two bugs that may be noticeable to authors.

Quotas

File quotas have not been successfully enforced in CMS since we began using it.  This meant that authors were able to upload more than the (default) file limit of 300Mb.

Now that the bug has been repaired, you may notice the error message that follows when/if you reach the configured file quota limit.

If this happens, you must delete files from the filelist to free space before more files can be uploaded.

Note that this does not change the maximum upload size per file, which remains at 25Mb.

Table classes

Since the upgrade last August, changing the table class from one class (such as stripeRows1) to another (such as border1) did not remove the first-selected class from the table.  To replace the class required first removing the class before choosing another.

That bug has been repaired by defining mutually-exclusive class lists so that the first class will automatically be replaced by the second selection.
