 After some extensive use of bookmarks to explore scattered areas on a map
 I found some problems with the Bookmarks tool as well as some missing
 functionality that is very useful to have. I am offering a patch to fix
 and improve Bookmarks.

 Here are the issues:

 1. a bookmark fails (silently) to store if it has a single-quote in the
 name (or project name). The quote mark is now escaped before inserting the
 text in the database.[[BR]]

 2. double-click on a bookmark item did not work (help says you can) due to
 an incorrect slot name. The automatic signal/slot binding didn't work
 because of this. This fixes #2774[[BR]]

 3. the stored precision of the extent was limited to 6 digits. I believe
 that full floating point precision (17 digits) should be preserved, so the
 number output precision is set to 17.[[BR]]

 4. have to delete a bookmark, then create a new one in order to update the
 extent. I have provided an Update button to do this as well as help text
 on its use.

 In the process of working out the coding for the fixes and improvements, I
 have: [[BR]]

 + reworked some of the Sqlite calls to simplify them as I found them
 complicated to understand[[BR]]

 + put the call to restorePosition in QgsBookmarks constructor instead of
 QgisApp. It makes little sense to have the main program call restore if
 the saving was done in the destructor.
