Adds tests and fixes for #183 and #184. This required changing one test (test_get_rvkc_by_keyword) which suggests that the change in behavior reported in #184 was intentional. But in retrospect it was a mistake, and the new approach is better.  Added a .rawvalue property to cards--on most cards card.rawvalue is card.value, but on RVKCs it returns the unparsed string value containing the full 'field-specifier: float' value.

Removed mention of #183 and #184 from the 3.0.10 changelog, since those issues don't pertain to the 3.0.x branch.

Added a test and attempted a fix, but this doesn't quite do the trick. Needs a little more thinking.

Fixes the issue, adds, a test, and a changelog entry.

Adding changelog entry for #180.

Adds a fix and test for #96

Adds a test for #151

git-svn-id: http://svn6.assembla.com/svn/pyfits/trunk@1829 ed100bfc-0583-0410-97f2-c26b58777a21
If primary headers will be allowed to have a name other than PRIMARY, they still need to be able to unambiguously report that they contain 'images' (really just non-table arrays though)

Moved much of the functionality for supporting EXTNAME and EXTVER out of ExtensionHDU and into the _ValidHDU class, since any valid HDU can support EXTNAME+EXTVER according to the latest version of the FITS standard.  By default the .name attribute for Primary HDUs still returns 'PRIMARY', but it may be overridden.

Added a changelog entry for the #151 fix.

git-svn-id: http://svn6.assembla.com/svn/pyfits/trunk@1832 ed100bfc-0583-0410-97f2-c26b58777a21
Rushed things a bit--never actually had the test for #151 passing or all the use cases implemented

git-svn-id: http://svn6.assembla.com/svn/pyfits/trunk@1834 ed100bfc-0583-0410-97f2-c26b58777a21
Adds one test that should help with this issue, though there should be more.

Fix a couple typos in the test. Also compressed image HDUs don't support sections (yet, though they might be able to by decompressing only the required tiles). In any case this shouldn't be tested for right now.

Copied some of the toughest tests of scaled image support and modified them to test compressed scaled images, and made several more fixes to get those tests working.  Most of those fixes simply required copying bug fixes over from the _ImageBaseHDU class leading to even more code duplication and support for my comments in ticket #88 that CompImageHDU really ought to be a subclass of _ImageBaseHDU, and not BinTableHDU.
