Fix attribute resolution in theme lookup

[Fixes Known Issues]
1. (CM) Chrome beta crashing w/ Hexo applied and menu button is pressed.
2. (AOSP) TextAppearance - fontFamily attr is incorrect (looked up in wrong package!) when
    a string value is defined in a style, and that style is set as the app's theme.

[Terminology]
1) Theme:    is the standard android definition of a theme.
             e.g in your manifest you may set android:theme="@style/foo"
2) CM-Theme: will be a Cyanogen theme. e.g. "Hexo"

3) Block: Also called index. Can be considered the cookie or ID to lookup a package in the resources.
          When a CM-Theme is applied, block 0 is framework, block 1 is the app, and block 2 is the
          CM-Theme.

[Background]
When a value for an attribute has not been found, the last resort is to look at a theme's base value.
This is done by using theme->getAttribute(...) which will return the value. The value is
unresolved if its a reference type. The block value will also be returned.

Since the value may be a reference and therefore unresolved, a call is then made to
ResTable::resolveReference(..) to do the final resolution. As part of its input, resolveReference
takes a block as a starting point.

In the case where resolveReference(...) is asked to resolve something that is not a reference,
for example, a string type, then it will simply return the same value and block. *Important* The block
value is then saved for the next call to get an attribute value. So if this block value is wrong
it will remain incorrect.

Therefore if resolveReference is passed the wrong starting block with a string value, then the wrong
block will be returned.

[Example]
1. 0x0101009b (android:attr/textColorLink) is first attribute to be looked up.
2. textColorLink has a value of 0x01020123 which maps to theme id 0x01020111. The block for theme
is "2" so block is set to 2. The value for this attribute is put into the array.
3. 0x010103ac (android:attr/fontFamily) is the next attribute to be looked up.
4. fontFamily is found in the theme as type string. The value is 0x7b9 (1977) and newblock variable
   is set to 1 since this value is found in the app's string pool. The block variable still == 2.
5. resolveReference() is called with block=2. The function does nothing and returns block=2.
   The fontFamily thus is stored wtih value=1977 and a block value of "2" instead of "0".
