v0.52

big progress made towards completing the login page!
also i'll be changing commits to look like actual changelogs

v0.52
general changes:
-i don't know why the tables page is updated but take it

login.vb:
-code now searches the 'un' column of table to find the value, and only
displays it in the datagrid
-it also takes that value in the 'un' column and puts it into a variable
in VB code! if nothing is found it returns 0
