Deleted duplicated strings, changed 'delete' icon.

I think this icon is newer and nicer than the previous one. :)

And once again i have few questions, i couldn't find any contact to you so I will post them here.
1. Why aren't you using github's "Issues" ?
2. Why the project still uses 

    android:minSdkVersion="7"
Google is not even providing us with stats for that, API 8 is used by 0.6% of all (Google Play connected) devices, i think it's not worth it and we could use API 10 instead. Also in the code there are several functions that are compatibility only in API 11+ so if whoever would really use Android 2.1 the app would crash..

BTW: Look at file "Osmand\OsmAnd\res\layout\drawer_list_sub_header.xml" Shouldn't there be EdiitText rather than TextView? I mean.. "inputType" in "TextView" rly? Something is wrong there..
