Extent "excludePattern" from file/folder level to path level

[simoncn]

I am working on this now. The solution is slightly different from my original proposal. In the solution I am implementing, each exclude pattern string can be one or other of the following:

1) a file name or directory name with wildcards (currently supported), for example:
## R*L ##

2) an absolute directory path without wildcards (new), for example:
/share/CACHEDEV1_DATA/Music Library/## ROEL ##

You can't combine these as a single value, so it is not possible to specify this:
/share/CACHEDEV1_DATA/Music Library/## R*L ##

As I understand it, the new option 2) will provide what you need. The change from my original proposal was needed to reduce complexity in the implementation and ensure good performance when scanning the library.

I will post back here when this change is available for testing.
