Migrate source files into src/ directory

This change moves source files into a src/ directory,
and puts object files into an obj/ directory. The Makefile
and xcode project are updated accordingly.

+   Sets the fg and bg color. May be called as often as you like, since
+   if the new color is the same as the previous, nothing will be
+   written. Negative values for set_color will also be ignored. Since
+   the terminfo string this function emits can potentially cause the
+   screen to flicker, the function takes care to write as little as
+   possible.
+
+   Possible values for color are any form the FISH_COLOR_* enum,
+   FISH_COLOR_IGNORE and FISH_COLOR_RESET. FISH_COLOR_IGNORE will
+   leave the color unchanged, and FISH_COLOR_RESET will perform an
+   exit_attribute_mode, even if set_color thinks it is already in
+   FISH_COLOR_NORMAL mode.
+
+   In order to set the color to normal, three terminfo strings may
+   have to be written.
+
+   - First a string to set the color, such as set_a_foreground. This
+   is needed because otherwise the previous strings colors might be
+   removed as well.
+
+   - After that we write the exit_attribute_mode string to reset all
+   color attributes.
+
+   - Lastly we may need to write set_a_background or set_a_foreground
+   to set the other half of the color pair to what it should be.
+
+   \param c Foreground color.
+   \param c2 Background color.
