#1145 heat.exe 3.0.3815.0 crashes with ArgumentNullException

[Dustin]

heat.exe website will crash with System.ArgumentNullException if there is a virtual directory that is the same as or under the home directory for the containing web site.

Repro Steps

1. Create a directory on disk with some name you pick.
2. Create a directory inside that directory.
3. In IIS administrator create a new web site called "new" and set the home dir to the first directory.
4. in IIS create a virtual directory on the web site you just created and set it's home directory to the main web sites home directory or the sub directory inside it.
5. run "heat.exe website new -out out.wxs".

Expected result: Heat can parse this into the appropriate fragements. (It's wacky, but IIS doesn't care)

Result:
Microsoft (R) Windows Installer XML Toolset Harvester version 3.0.3815.0
