Merge pull request #194 from Arthaey/master

Added more dependencies for building under *nix.
Default pixmaps are now tango. Old pixmaps retained as the 2012 theme.

Expanded out the zip files for pixmaps. Simpler to have them in
directories of their own and the build system not expand zips or
whatnot. Whichever theme you select is the one that the pixmaps will
be installed for. All pixmaps are shipped in the tarball.

Added macports Portfile for central keeping: This is the golden copy
of the file and should always be considered the latest. All my other
fontforge Portfile files just softlink to this golden copy.
Some nice fonts for a font program!
new function to find pixmap dir
try to load the resources file form the pixmap dir if there is no set theme.

When the metricsview is open and the user decides to draw a shape in the
class of a rectangle (cvshape) then suspend live updates to the metricsview
until the shape has been completed (ie, the mouse button released).

Something is treading on its own feet in the live update process here. The
core of that is triggered by MVRegenChar() in the two lines of BDFCharFree()
followed by NULLing the mv->show->glyphs[sc->orig_pos]. If those lines happen
then the shape is no longer drawn properly in the active charview and things
are generally not what the user expects.

When the metricsview is open allow things like rectangles to still be drawn in the charview.
Fix apparent typo in call to utf82u_strncpy.

The original author must have meant ubuf+1 and not ubuf-1, in order to
preserve the space previously inserted at index 0 of ubuf[].

Hmm, git add seems to have been forgotten at some stage :(
