patch: selection-unfuckHEADmaster

This patch addresses two issues with selections in st.

First, the SelectionClear signal from X is no longer ignored.  So, if
another selection is made in another window, st's selection will
disappear.

Second (and this one is more of a personal preference), new selections
that begin after the end of a line are now considered to begin at the
start of the following line.  This makes selecting a group of lines
easier for either copy/paste or readability in the terminal.  Previously,
the newline character from the preceeding line would be included in the
clipboard and the dead-space at the end of that line would be
highlighted.
