Use File System as SCM.

Simulate File System as SCM by checking file system last modified date,
checkout(), pollChanges(), ChangeLog and distributed build are all
supported.

Folder difference is found by

1.  for each file in source, check if the corresponding file in
    workspace exists
    1.  if not, it is a new file
    2.  if yes, further checks if the file in source is newer than file
        in workspace, or if source file is modified since last build,
        this is a modified file
2.  for each file in workspace, if the corresponding file in source does
    not exist AND
    1.  it is in our self maintained "allow delete list", we will delete
        this file from workspace. Every times we copy a file from src to
        dst, we add the filename to the "allow delete list", in other
        words, we will only delete files that are copied by us

Filtering is supported when checking for modified files.

If ***Clear Workspace*** is checked, the system will delete all existing
files/sub-folders in workspace before checking-out. Poll changes will
not be affected by this setting.

In Changelog, ***User***, i.e. who changed the file, is not supported.
