(.gitignore) ignore thunar.a
MR !268 Since !153 is merged, thunar.a, which is a fake library used for generating documentation, has been managed by make but not been covered by .gitignore. This has caused useless yet big file thunar.a keep appearing in commits that included files with "git add --all". This commit adds thunar/thunar.a to .gitignore to fix this issue.
