The PM fails to recognize existing plugin's directory in the prefix if it contains as slash

[SebastianAdams]

The PluginsManagerLauncher program attempts to modify the config.bbj file to include the pluginsHome folder in the PREFIX.

However, the comparison on line 221 checks to see if directory$ = pluginsHome$ is always failing because the directory$ variable includes a trailing slash which is not present in the pluginsHome$ variable.

Since most prefix entries typically do include a trailing slash, the program incorrectly reports that the prefix needs to be modified to include the pluginsHome$ folder.
