This deprecated CharAt and CharCodeAt for being unsuitable for text processing and in the case of CharCodeAt also for being buggy.
A new replacement, ByteAt has been added that reads a string byte by byte, as well as CodePointCount, which counts the amount of Unicode code points in a string and GetNextCodePoint which reads the string code point by code point.
Note that while this woll work as intended with the currently supported languages as a means to read single characters, there is no guarantee that this will remain so if Unicode support gets extended to things which break the "one code point == one character" assumption.
Some reorganization to avoid code duplication plus making the log screen capable of using the generic font. This also means that the popup for the log in Strife's status bar will be disabled when in generic mode - this popup with its special font would be a bit problematic.
Parts of this menu suffered badly from lack of screen space to convey the intended information due to the oversized fonts. With the new font this is a lot less problematic (unless using 320x200, of course)
