Initial zh_TW translation
Merge branch 'master' into zh-tw-trans
Update zh_TW translation

Previously used translation for "variation" (種類) conflicts with usages of
"type" (as in "card type") and "category" (both 分類 and 種類 were used).
Switch to use "規格" for "variation" (as used by pchome.com.tw), and unify
"category" translation to use "分類".
All strings are now translated
