I have corrected the tags file format of ctags in .gitignore. I have closed the previous pull request because I have sent some extra commits which I have fixed.

Please check this commit because when I used ctags with this project, tags file was generated which was not being ignored by .gitignore. So when I checked the .gitignore, there was a ctags column but the '.tags' things was not hiding any files. Therefore, I deleted that line and added the tags file in the .gitignore. If there are any suggestions, then please suggest I would change them.

I still have .tags files. I haven't built them in a while so I'm not sure if the naming has changed but I wouldn't recommend removing it to prevent someone else committing the tags accidentally. Since they are tags for you, just add it to the .gitignore file.

@bigharshrag Added the .tags file as you suggested
