- Fixed check and error handling. Moved them to seperate functions to be more organized.
- Added userid search
- Added Tweet limit (Pulls tweets in incriments of 20- i can't modify that).
- Added counter (Display number of tweets collected at the end.)

Fixed Spacing bug

add hashtags extraction and cleanse text (urls)

Made hashtag display indicated by arg rather than being displayed by default.

I added an automatic extraction for hashtags, and a space character before http, https and pic urls in the text column, in order to parse it more conveniently.

Fixed typo.
