Enable attach in lldb
Enable attach in lldb

Attach wasn't working with lldb on linux because lldb ends the
attach process in break mode whereas gdb ends in run mode. Issue
a continue after the attach in lldb to make the behavior match
gdb.

NOTE: if externalConsole is not enabled, and you issue an
attach, the elevation dialog will not be displayed. This will
need to be resolved at some point.
