mod_invites_page: Change client selection button text from 'Install' to 'Select' by default
This also allows specific clients entries to override the text via the 'select_text' field.
Rationale:
1) users may already have the software installed, we still want them to select it anyway
for the tailored setup experience.
2) some clients (e.g. web clients) are not really "installed" so the text was misleading
