獲取IE瀏覽器的版本，獲取默認瀏覽器的安裝路徑，獲取主流瀏覽器的安裝路徑

1.隨著IE9之後，IE8和IE10獲取瀏覽器的版本發生了變化，裝了IE10,IE11后註冊表Version的值都是9，@”SOFTWARE\\Microsoft\\Internet Explorer\\Version Vector”的版本也是9，svcVersion值才是正確的版本

2.默認瀏覽器的安裝路徑，目前也不統一，瀏覽器自帶的設定默認瀏覽器可能也是無效的，註冊表：Software\\Clients\\StartmenuInternet\\和http\\shell\\open\\command地方會記錄，瀏覽器自帶設定有的會修改兩處，有的只修改了其中一處，所以判定也不是很準，大家自行決定，Win7設定前者值，XP電腦修改了兩處，QQ瀏覽器設置的後者

3.獲取主流瀏覽器的安裝路徑，大部分安裝程式會在註冊表@”SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths”里，也存在一些列外，只在自己的註冊表里記錄，此處測試了  
chrome，360，baidubrowser，firefox，iexplore，ucbrowser，sogouexplorer.exe，qqbrowser，Opera
