2 Typos Fixed + Punctuation
Minor typos fixes in English GUI text: a "tor" instead of "for", "ancoding" inst. of "encoding". Also added 2 missing fullstops in Tooltips, for consistency sake with other Tooltips punctuation style (Qt Linguist nags you when a translations doen't end with same punctuation as original, so it brought them to my attention during translation work).
