SobekCM.aspx simplification and Admin Wordmarks Update

- Previously, the SobekCM.aspx had TWO forms, one which would be used when there was a file upload possibility and then the other form.  Each of these had multiple spots for also directly writing HTML to the output stream in them.  Removed the separate upload form completely.  Same single form is used for all operations now.
- Change above required change to the admin and mySobek HTML subwriters and many viewers as well
- New flag in the abstractHtmlSubwriter class allows any subwriter to indicate if the form needs to be configured to allow up load ( i.e., encryption type of 'multipart/form-data')
- This required updates to all mySobek and admin views which allowed uploads (also did some parameter name refactoring at the same time)
- Corrected issues with some of these views not showing the footer correctly ( bookshelf and logon in particular )
- Wordmarks Admin View
   - Updated to HTML5, and cleaner CSS
   - Added ability to upload a new wordmark
   - When adding a new wordmark, you select an unused image file from list now
   - Can also delete unused image files from the wordmark directory now
   - When deleting a wordmark/icon from the database, the image file is now also deleted
   - Wordmark types include .jpeg, .jpg, .bmp, .gif, and .png
