removed frame numbering from BLI_convertstringcode into its own function (BLI_convertstringframe), many uses of BLI_convertstringcode were passing dummy frames values anyway.
in cases where adding the current frame number to a filename is needed run BLI_convertstringframe(...) after BLI_convertstringcode(...)
There are some cases Im not sure BLI_convertstringframe is needed, these have been commented as todo, but at least have the same functionality they used to.
* BPath sequencer strip looper was only operating on the active scene, now look through all scenes.
* The active sequence strip wasnt being reset when scenes switched, so you could see the previous scenes strip when switching to a new scene.
Added BLI_split_dirfile_basic, that only splits the path into directory and file. without checking the dir exists or creating it, without changing the original string that is passed to it.
This means when moving large projects with many images/videos/sounds is possible with 'File, External Data, Find Missing Files'.
- needed so we can put peach animatic, glrenders & testrenders on the dvd.
also datatoc.c - brecht's fixes from apricot.
made when testing peach blend files wont have path issues when sent to the renderfarm.
* log failed path conversions
* clean the path so //foo/../foo/ is removed (not sure why but some peach files had this problem)
Also added a function to util.c
BLI_cleanup_file, same as BLI_cleanup_dir but dosnt add a slash at the end.
Useful to use before sending blend files to the renderfarm.
* Make all Paths Relative - makes any absolute paths relative.
* Report Missing Files - creates a textblock listing all missing files.
* Find Missing Files - searches a directory recursively for filenames that dont exist at their current path.
Added a path looper type and functions that currently loop on image, sound, font and external library paths.
