Improve Simplified Chinese Translation

Some of the translations look a bit strange and seem to be translated by machine.

So I modified some of the translations according to the usage habits.

Example:	English	Original Chinese	New Chinese	Reason
Asking permission for ROOT access…	要求获得ROOT访问权限…	请求ROOT权限中…	"要求" is to aggressive.
Empty	Empty (Not translated)	空空如也	Add a suitable translation for various activity(filter/saved logs…).
Clear	清楚	清除	A typo.
Appearance	出现	外观	The original is translated as a verb(appear).
Super Dark Theme	暗色主题	纯黑色主题	"Dark" and "Black" are confused.
Max recent logs to keep in memory	最多可保留的最近的日志	在内存中保存的最大日志数	The "in memory" isn't translated.
