Code Issues Releases Wiki Activity

ITextLink moved to ClickHandler, TextLinkPtr > ClickHandlerPtr.

Browse Source 
Global methods textlnkOver/Down/DrawOver were replaced by
static members of ClickHandler, now global state consists
of the handler pointer + host pointer, who declares callbacks
for the active and pressed handler changed events.

This will allow to use ClickHandler from different hosts
simultaneously (like HistoryItem / BotDescription / BotKeyboard).

Not yet tested.
