add table-size-test
* Makefile.am (noinst_PROGRAMS): add table-size-test
* .cvsignore: add table-size-test.
* e-cell-text.c (ect_ecent): use e_table_model_is_cell_editable
instead of E_CELL_EDITABLE.
* e-cell-toggle.c (etog_event): same.
* e-cell.c (e_cell_init): don't call e_cell_set_editable. that
info comes from the model.
(e_cell_set_editable): removed function.
* e-cell.h: remove the E_CELL_EDITABLE flag. that should be
retrieved from the model. also, remove the prototype for
e_cell_set_editable.
* e-table-size-test.c: new file, for a stress test of sorts, of a
large, uneditable e-table.
