Misspelling of Seriall in UART causing failure to compile

[calumapplepie]

Apparently, in the UART part of the arduino library, Serial is spelled Seriall. No idea why: the only reason I noticed was not because I was actually using UART, but because when the arduino IDE includes a library, it includes all members. Therefore, arduino projects will refuse to compile unless you remove the UART header.

Also, its done several times in the header, but only in that header.
Just thought I'd mention it.
