* Disabling transform timeout

* Adding a comment explaining the TRANSFORM_TIMEOUT and when to remove

* Disabling the costmap movement callback.

This callback produces lots of error message noise. It also has no
actual function and should be removed. It sets a couple of variables
on the costmap object, but nothing actually reads those variables.

* Removing movement callback from costmap_2d_ros

It had no effect. It set variables that were unused in the rest
of the system.

Using Visual Studio Code, I've been opening just the directories that I'm interested in, avoiding the output directories (install, build, and log). In this configuration, when debugging various modules, the VS Code app will put .vscode files in each source directory being debugged. This causes the 
 directories to be highlighted in the editor indicating that files have been added. With this addition to .gitignore, these files will be ignored and the VS Code editor will more accurately reflect any changes to the workspace.
