Build Integer from Unicode

[videlec]

Currently, Sage fails to build Integer from Unicode

sage: Integer(u'1')
TypeError Traceback (most recent call last)
...
TypeError: unable to coerce <type 'unicode'> to an integer

The two lines patch attached to this ticket, allow such feature

sage: Integer(u'1')
1
sage: Integer(u'0X13')
19

Component: basic arithmetic

Keywords: Integer, unicode

Patch fixes the reported problem. Did 'make testlong' and all tests passed. Positive review!

1. The commit message of the patch should be changed.
   2. Could you give a less trivial example in the doctest? At least something with more than one digit and something hexadecimal (Integer(u'0x2A')) or so...

Applied patch, did 'sage -b' and 'make testlong'. All tests passed. Positive review!
