community/mate-applets: stickynotes-applet not provided and not usable

On most distros, MATE can have sticky notes, but on Alpine Linux and Gentoo the sticky notes icon can't spawn sticky notes and it crashes if you try to spawn a sticky note and then double click on the icon, and on Alpine Linux you have to install gtksourceview-dev, then remove --disable-stickynotes from the ABUILD and recompile it in order to see the icon to begin with.

How to reproduce the crash:

• if necessary, recompile mate-applets without using --disable-stickynotes
• right click on a MATE panel->Add to Panel->Sticky Notes->Add->Right click Sticky Notes Icon->New Note->Double click Sticky Notes Icon

How to reproduce the backtrace:

• if necessary, recompile mate-applets without using --disable-stickynotes
• compile mate-applets and libx11 with debug symbols and unstripped
• open a shell and type this:

gdb /usr/libexec/stickynotes-applet
run

right click on a MATE panel->Add to Panel->Sticky Notes->Add->Right click Sticky Notes Icon->New Note->Double click Sticky Notes Icon Type this in the shell:
