Fix misc bugs w/ IDE build in folders with a space

- Add quotes to bin/msbuild.bat paths
- Tweak PostBuildCmds in Debugger64 and IDEHelper
- Tweak Debug paths in IDE project to be relative to Workspace
- Modify AppendWithOptionalQuotes to not add more quotes if source string already in quotes
- Modify quoting behavior in build shell command construction
