[LSMASH Indexer] show time/file progress during indexing
                 added possibility to set output file/folder
                 blocked indexer if input file is in a read only directory
                 lowered the default priority so that it will be used after FFMS
                 added log information
                 copy the runtimes if required
[FFMS Indexer]   defaults to LoadPlugin if LoadCPlugin is also possible
