Embed run-time option doesn't prevent namespace collisions

[Chuck.Esterbrook]

Using the -embed-run-time:yes (or -ert:yes) option on the command line with DLLs leads to problems later when 2 or more DLLs are referenced in the same application. They will collide on the namespace "Cobra.Lang."

This is especially problematic because -ert:yes is the default behavior.

[Chuck]

The likely solution is to mangle the name of the "Cobra.Lang" namespace into something private. This could be the appending of the MD5 hash of the current date/time and current directory.

The CobraLang.cobra and CobraLang.cs files would likely need to be copied with the name mangling done to the copies.

[Chuck]

The run-time library is now divided into several files located in the Cobra.Lang subdirectory. Copying files just to change the namespace seems rather inefficient. Another approach would be to provide an internal "namespace name replace" feature in the compiler.
