Minor usage errors/bugs

[DominicRossillo]

minor:
1.main page: when clicking on bottom tabs, scroll down screen to see the new text.
2. track statistics box is slightly smaller on y axis
3. Register page: says at lest one number but it actually requires atleast 2
4. Register Page: if you register with a entry that already exist you get an error but there is no error message in it.
a. would need this fix for user name exists, email address already used
b. if you put in invalid characters for first name it gives a blank error
c. Can set my first name to "$$$" is this something we want to prevent or do we not care about first name and last name input.
5. submit a report: if you put a very large number of characters in the fields you will get a Your report was unable to be submitted, please try again. Got a packet bigger than 'max_allowed_packet' bytes. instead maybe put a character limit on the description of the issue box to avoid people submitting the report and then getting an error that deletes all their text on the page. Also if its too long it exits the bounds of the report box for admin.
6. My Account: you can change your password to your current password, might want a check for that?
7. Your Collection: should have some text displaying" you have no Texts currently" or something like that
8.On view text page: if the text that gets paste in has a hyper link you get the blue text but also "href=" before the link and some tags
9.on view text page: some words don't return anything for the see usages button
10. For stats we also may just want to only add unique word look ups to safe space in the long run.
11. If you hit get started on index.php while logged in it will bring you to log in page. should make it send you to my classes or something
12. You can make a text with no title.
13. if you try to remove nothing it will still ask you are you sure. should make it hide the box if there is nothing assigned.
