Add context menu extensions

[AlenPelin]

We need to add a couple of context menu extensions:

For web.config

• Sitecore ConfigBuilder / Open showconfig.xml build showconfig in temp folder and open it
• Sitecore ConfigBuilder / Open showconfig.xml (norm) same, but also normalize temp file
• Sitecore ConfigBuilder / Open web.config.result.xml same, but also merge with web.config
• Sitecore ConfigBuilder / Open web.config.result.xml (norm) same, but also normalize temp file

For *.config

• Disable configuration file add .disabled to file extension

For *.disabled | *.example

• Enable configuration file change extension to .config

Added functions to Disable, Enable config-files; There was issue in creating root-element for sub-elements for context menu. After updating dlls to SIS 1.3.2.1, SCB 1.0.1.0 , the tool has stopped working. After fixing this, I'll make first part.
