Actions only for a specific configuration of solution

[Denis Kuzmin]

Need a support to handle events only for selected configuration. For example:

• DTE operations (currently there are no variants) -> run all test on old VS2010 (where not present this option as 2012 or 2013) only if selected the Release configuration etc.
• Files & Interpreter modes - only with another handling i.e.: <script> $(Configuration)

[Denis Kuzmin]

Implemented: the Actions only for a specific configuration

• Closed Issue #16
• Introduced the IEnvironment as layer for work with the DTE-enviroment and for other similar
• • The Environment implemented this as main worker. In general, main logic splitted from MSBuildParser.
• Config no longer static now.
• UI.EventsFrm contains logic for #16 and #18
• . #18 partially prepared:
• • The bindProjectPre() & bindProjectPost() currently throws exception as a "not yet implemented"
