Add New Task Button one columns and Pane Bar

There will be add button on Columns like Today, Tomorrow and on namedTag type of columns. So when the tag is added it will show up under this columns and those specific properties will be auto added.
Inside the Modal, there will be dropDown button to select the file in which the user want to add the task, it will be added at the end of that file. Use below code to get the latest files, which you show on the first section of the dropDown options. If use couldnt able to find it there, then show all the other files in the options :
```
app.vault.getMarkdownFiles();
app.workspace.getLastOpenFiles();
```
There will be also option to create a new TaskFile for this task. Now TaskFile is a special type of file, where the file will start with the h1, which will be the title of the task, followed by the properties with certain format and then as you will be integrating the commenting functionality. Those comments will be added in the same file as well.
- Create an option in the settings, where to store all the TaskFiles by default, the user will then can change the location of those files and more them other places. I guess, i might have to change the extension or something to make the files recognizable, like fileName.tb.md.
