Result of hacking night:

* HtmlAgilityPack works now under Mono
* added a VillageData struct to save all village-related data (like troops, buildings, etc.)
* added _data, in which we can save all data regarding multiple villages
* added two parsing methods (Parse.parseOverview to get village IDs, TribalWars.parseVillage to retrieve information from an individual village to populate _data)
* minor code changes
