Cleanup done while researching the Boost Jam internals. Added better implementation description comments at many places. Cleaned up the 'dependant' and 'dependency' terminology that got mixed up in several places. Renamed several functions to use underscores as word separators.

Bug was happening when we had a multifile action that got triggered to build its non-initial target. Then while that action was being executed all the other targets were reporting as 'already built' and were getting used by other actions prematurely. Quick-fixed by making all targets built by a single action list each other as 'included' causing anything else depending on any of these targets to automatically depend on all the others in the group as well.
The solution is not perfect as it might have some unexpected interactions with other uses of 'included' targets and now if any target in a group is not up to date then all of them will be rebuilt even if actually did not need the target that was up to date. On the other hand this should be a really rare use case as it would require the one target in a group to be up to date and be needed while another in the same group (i.e. built by the same action) to not be up to date.

When scanning directories and creating a list of all their content (filent.c) it would identify all the located files and folders using their long file names. On the other hand, referencing a target using its short file name inside a Jam script caused Boost Jam to reference those files twice using two separate TARGET structures - one identified using the file's short name and one using the file's long name.
One bad example was the MkDir which would always attempt to create a folder identified by its short name even if that folder already existed (due to the NOUPDATE rule getting applied on the incorrect TARGET).
The change does not affect targets whose names do not represent existing file names.
Also, it seems to me that the short_path_to_long_path() call in file_dirscan() in the filent.c module should most likely be moved to file_info() in the filesys.c module. This would make mapping file names to file_info_t & TARGET structures consistent. However, I have not done this in this patch just to make the patch as minimal as possible.
Prepared tests have been do nothing on non Windows platforms.
