Renaming skins/base back to skins/default to unblock I10n.

Revert was requested by Q.

Fix for EXT-5120 "Mouse-up in the scrollbar to the right of a link in nearby chat window opens the link".

Added an optional bool parameter "hit_past_end_of_line" to LLTextBase:: getDocIndexFromLocalCoord() and getSegmentAtLocalPos().  Default is true, which gives the old behavior.  If false, clicks past the end-of-line won't map to the last segment on the line.

Made LLNormalTextSegment::handleHover(), handleRightMouseDown(), handleMouseDown(), and handleMouseUp() call getSegmentAtLocalPos() in this new mode before processing URL actions, and only do the processing if it returns the same segment.

Added versions of LLFontFreeType::getXAdvance() and LLFontFreeType::getXKerning() that take LLFontGlyphInfo* instead of llwchar.  This allows code in LLFontGL that already has the LLFontGlyphInfo* to pass them instead, saving calls to LLFontFreetype::getGlyphInfo.

Changed the index on the keyword map in LLKeywords so that LLKeywords::findSegments() doesn't have to create LLWString objects to search the map.

Review #114
This (mostly XUI) change moves the prefs checkboxes out of the nearby media panel and into the prefs floater. The "Sound" tab is now the "Sound & Media" tab, and its layout has been modified drastically to match https://docs.google.com:443/a/lindenlab.​com/Doc?id=ddznhrqn_34kcxdz8f3#​Preferences

Set global height attributes for buttons, combo boxes, and flyout buttons as part of cleaning up the widget test floater for QA testing. Removed in-line height settings in the floater xml.

We were pushing off redrawing your local texture composite
while waiting for a baked texture cache response from the server.
If this happens when your textures come in, your avatar will de-cloud
but the composite will not update, resulting in nudity.

Changed the logic so we will re-generate a local composite even if
we have a pending baked texture query (we still suppress uploading the
composite until a response is received). Verified several times that this does
fix the issue. Will update the JIRA with reliable repro.

Q verified issue is worthy of a hotfix checkin

This is necessary for new user experience. Patch should be contained enough to be low-risk. Contact Nyx if any further questions.

Url substitutions now support a [FIRST_LOGIN] parameter that returns
the value of gAgent.isFirstLogin(). This now gets passed to the Home
