Optimized .myBookmarksAddButton + added debug for console.log output

- Optimized code for checked ticked bookmarks when .myBookmarksAddButton
is pressed.

- Added if(debug) statement around console.log code that was left open.
Removed 'selected' attr + Optimized '#saveChangesSelectedLinks'

- Removed the attr id adding 'selected' to selected links as updated
JQuery handlers do the job.

- Optimized '#saveChangesSelectedLinks' by removing unnecessary if
statements.
Added Feature: Bookmarks with same names

- If they have the same names but different URL's, we will add both.

- If they have the same name AND the same URL's, we will only add one.
