[UX] Consistent wizard message texts

- Sentences finished by dot.
- Renamed WizardNewXtextProjectCreationPage_LabelFacets to
AdvancedNewProjectPage_LabelFacets since it belongs to the advanced
page.
- Renamed 'Plugin' to 'plug-in'. This is how it is spelled in Eclipse
wording.
- Renamed 'eclipse' to 'Eclipse'.
- 'Xtext Project' -> 'Xtext project'
