Eeschema: fix many append schematic bugs. 

Do not add cache library from another project to old library list.  This
is wrong and can cause all kinds of symbol library linking issues.  It's
better to force the user to fix broken symbol library links than the false
security of using multiple cache libraries.

Use correct paths when appending schematic outside of the current project
path when hierarchical sheets are appended.  If the path can be relative,
give the user the option to use either relative or absolute paths.

Do not change symbol library names in schematics appended from a source
outside the current project.  This will almost ensure the symbol library
links will be broken in the source project.

When the appended schematic is from another project, attempt to check all
of the possible combinations of symbol library table importing that could
cause broken symbol library links and give the user the option of canceling
the append operation or live with the possibility that there may be broken
symbol library links.

When the append schematic is in the current project path but not part of
the schematic, check to see if there are any library nicknames that do
no exist in the project symbol library table and give the user a chance
to cancel the append process.
