[ADD] Support for projects and tags ==> @project and #tag. Project(s) name(s) will be always added at the beginning of the task name, while the tags will be where they were added
[UPDATE] Now the task name will always have the first letter uppercase
[FIX] Task name textbox is now larger
[FIX] Finished tasks are now also removed when the user clicks the "Clear All" button
[FIX] A little bit of code-cleaning
