Neat 0.1.10: Nothing Important

Mostly a bunch of small fixes that have cropped up over the last week.

• Always set -fno-strict-aliasing. This "fixes" some C backend bugs that happened with -O. Apparently we're supposed to use unions to pointercast data structures? Man, fuck that though.
• Add union type, C import union parsing. This means the (int, int, int, int, int) hack isn't necessary anymore.
• Add std.stdio.byLine.
• Add std.algorithm.cumulativeFold.
• Add array .dup.
• Add 32-bit build. Note this is not very tested.
