Alpha build v1.0-19

Check whether we still have read and write permissions for a Base SAF directory before registering and every time before creating a new file inside the SAF base directory. Log any failures.

Alpha build v1.0-18

Check whether a base directory exists when returning a new AbstractFile in newBaseDirectoryFile()

Alpha build v1.0-17

Remove lots of unnecessary checks from the isChildOfDirectory() and areTheSame() methods

Alpha build v1.0-16

isChildOfDirectory() function prototype

Alpha build v1.0-15

When checking whether a base directory already registered skip the base directory we want to set the new path because that directory can have the new path even if it's exactly the same (because this directory is already owning this path)

Alpha build v1.0-14

Add couple more overloaded versions of isBaseDirAlreadyRegistered method

Alpha build v1.0-13

Implement isBaseDirAlreadyRegistered method to figure out whether we already have this directory registered as a base directory (every base directory should have a unique path!)

Alpha build v1.0-11

Yet another fix, now compare with storage ids
