Switching to v1.x format instead of v1.0.x

Update some images and project description.

Finished with alternate search directories for location source file.

GDB has its notion of where source files live. Sometimes this is
incorrect as the source may be in a different place after the executable
is released.

Seer's source search feature is a list of alternate directories to look
in if the path that GDB knows of doesn't exist.

Use the Config dialog to set them. Then save the config.

This is a global feature. That is, it applies to any and all executables
being debugged. (Perhaps I'll add project based session files to handle
per executable settings).

Changed org name to "Seer" so the config file would be in a better named

directory.

Increment version number.
