Huge "ChallangeFriends" Update:

javascript.js :
- Added 2 "Consts" relevant to the ChallangeFriends page
- Added 2 global fields:
m_FilterredChallangeData - general list to get players from (will hold
the relevant data of Invite/Exisiting/Filtered(by the search bar)
players
-Splitted the old Invite page functions with the new page's function. It
involved a lot of changes, but the core is very similiar
*** 2 Main differencts: **
1. Canceled the "Search" button for the search bar, now the search
refreshed every time the search box's value is changed (easier to the
user)
2. Removed the "Show more players" button, now we detect that the scroll
bar almost is in the end of the freinds list and loads 20 more if there
are more players to load
