std.string will get the boot

I've been thinking about characters lately and have realized that 
tolower, toupper, icmp, and friends should not be in a string library. 
Those functions need an "alphabet" to be useful; not language, nor locale...

In fact, the character itself must have alphabet information. Otherwise 
a string like "ali & jim" cannot be converted to upper-case correctly(*) 
as "ALİ & JIM". And the word "correctly" there depends on each 
character's alphabet.

Similarly, two characters that look the same cannot be compared for 
ordering. Comparing the 'x' of one alphabet to the 'x' of another 
alphabet is a meaningless operation.
