Code Issues Releases Activity

poc: add file browser for NCA FS sections.

Browse source 
Takes advantage of the recently implemented devoptab interfaces. Supports individual file dumping and multiple file/dir dumping via highlighting. May possibly need some additional testing. The code could potentially be improved, but I'll look into it at a later time -- I just want to release this now.

Other changes include:

* devoptab: comment out log messages.

* utils: add utilsGetDirectorySize() function.
