Fix various presentation and build bugs

Renamed the href in various jsp pages for the main styles page from
Styles to styles, as the web browser is case sensitive.

The session attribute of id was changed to uid, and the bid and vid
attributes were removed to be the generic account id (aid). To identify
the account type, another session attribute editing_account_type was added
to the project. Several different classes were changed so that they use
these new attributes as opposed to the old ones.

The page editVeteranProfile had the action and form input names changed
so that it can be used with the Login servlet.

The MySQL class has the getPreparedStatement function moved. Several
functions were changed to just get the prepared statement from the
database connection. Also, the get businesses function was changed to
an array list, and several different query bugs were fixed.
that dealt with renamed session attributes.

The Divisions class was deleted as it is not currently used by any of
the other files in the project.
Modify Header to use generic account types

Modified the header include so that checks the aid for a logged in
account instead of either a vid or bid. To determine what account
is being used, the editing_account_type session variable is checked.

The Login servlet was also changed to use generic account types as
opposed to a bid or vid session variable.
Add logout functionality

Added servlet to log a user out of it's current session. Also updated
the header file to have a link to the logout servlet.
Fix bugs with NewBusiness page.

Removed include of a file that we deleted.

Renamed the Styles.css link to styles.css.
Change link paragraphs in index page.

Changed the link paragraphs to have different text for their associated
locations. Since the text has more lines of text, extra padding was
added to the body section css selector.
Remove unneeded javascript

Removed JavaScript code that was commented out, but not removed. It
is no longer needed.
Change redirect for question page.

Changed the redirect logic for the question page so that not can
businesses view the page, but the veteran that created the page can
view it as well.
updated ignore to ignore log file

Removed the unneeded Roster class. Tags are done in a different
fashion, so these are no longer needed.
Merge remote-tracking branch 'origin/master' into HEAD
