Bug 537632 - Meson Property Pages missing some fields after configure

Browse source 
- fix MesonPropertyPage logic concerning a configured meson project
- for possible values, add "-" and "/" as valid characters
- in state flow, don't just wait for blank lines, an option
  header can occur in the middle of a group or a new option group
  name can also occur
