Issue in getInsertedMentions() method

[kashifo]

Hi, While using your library i encountered a flaw in this scenario

When user scrolls backwards and adds new mention in between of text, on send button when we get inserted mentions to process, you are giving mentions in the order of their insertions (the mention added in between later is coming at last) - that's not right for post-processing, you should give list of mentions in the order of their appearance in the edittext.

Why post-processing is important: because in it programmers may process insertions like for example constructing them in HTML format.
