[Projects] [nolimips: 123] Handle options waiting for an integer

Index: ChangeLog from Benoît Perrot &lt;benoit(a)lrde.epita.fr&gt; Handle options waiting for an integer. * src/task/task.hh, src/task/task.cc: Add a "needs a value" flag. * src/task/task_register.cc: Handle values from command line. * src/task/int_task.hh, src/task/int_task.cc: New files. * src/task/Makefile.am, src/task/libtask.hh: Distribute new files. New files.
